NFC: 3.20 first pull request

This is the first NFC pull request for 3.20.

With this one we have:

- Secure element support for the ST Micro st21nfca driver. This depends
  on a few HCI internal changes in order for example to support more
  than one secure element per controller.

- ACPI support for NXP's pn544 HCI driver. This controller is found on
  many x86 SoCs and is typically enumerated on the ACPI bus there.

- A few st21nfca and st21nfcb fixes.

This patch introduces run-time board detection through DMI and MAC-PHY
configuration function used by quark_default_data() during initialization. It
fills up the phy_addr for Galileo and Galileo Gen2 boards to indicate that the
Ethernet MAC controller is or is not connected to any PHY.

The implementation takes into consideration for future expansion in Quark
series boards that may have different PHY address that is linked to its MAC
controllers.

This piece of work is derived from Bryan O'Donoghue's initial work for Quark

Struct mlx4_vhcr was implicitly padded by the gcc compiler on 64-bit
architectures.

This commit makes that padding explicit, to prevent issues with
changing compilers and with incompatibilities between 32-bit architecture
implicit padding and 64-bit architecture implicit padding.

This structure is used in virtualization for communication between
the Host and its Guests. The explicit padding allows 64-bit Hosts
(old and new) to continue to interoperate with 64-bit Guests (old and new).

However, without this fix, 64-bit Hosts could not interoperate with 32-bit
Guests (since these did not insert the padding dword). With this fix,
32-bit Guests will be able to interoperate with 64-bit Hosts (since
the structure offsets will be identical on both).

In the past, the spec indicated that there were several classes of timeout

We leave the class differentiation in the driver as-is (to protect against any
future spec changes), but set the timeout for all classes to be 60 seconds.

In addition, we fix a few commands which had hard-coded numeric timeouts specified.

The reserved lKey is different for each VF.
A base lkey value is returned in QUERY_DEV_CAP at offset 0x98.

The reserved L_key value for a VF is:
    VF_lkey = base_lkey + (VF_number << 8).

This VF L_key value should be returned in QUERY_FUNC_CAP
(opcode-modifier = 0) at offset 0x48.

To indicate that the lkey value at offset 0x48 is valid, the Hypervisor
sets a flag bit in dword 0x0, offset 27 in the QUERY_FUNC_CAP wrapper
function.

When the VF calls QUERY_FUNC_CAP, it should check if this flag bit is set.
If it is set, the VF should take the reserved lkey value at offset 0x48.
If the bit is not set, the VF should not use a reserved lkey
(i.e., should set its reserved lkey value to 0).

For this patch series there are no userspace facing changes, a diff between

This patch attempts to fix the following problems when an actor or
partner's aggregator is not active:
    1. a slave's lacp port state is marked as AD_STATE_SYNCHRONIZATION
       even if it is attached to an inactive aggregator. LACP advertises
       this state to the partner, making the partner think he can move
       into COLLECTING_DISTRIBUTING state even though this link will not
       pass traffic on the local side

    2. a slave goes into COLLECTING_DISTRIBUTING state without checking
       if the aggregator is actually active

    3. when in COLLECTING_DISTRIBUTING state, the partner parameters may
       change, e.g. the partner_oper_port_state.SYNCHRONIZATION. The
       local mux machine is not reacting to the change and continue to
       keep the slave and bond up

    4. When bond slave leaves an inactive aggregator and joins an active
       aggregator, the actor oper port state need to update to SYNC state.

st21nfca has 1 physical SWP line and can support up to 2 secure elements
(UICC & eSE) thanks to an external switch managed with a gpio.

The platform integrator needs to specify thanks to 2 initialization
properties, uicc-present and ese-present, if it is suppose to have uicc
and/or ese. Of course if the platform does not have an external switch,
only one kind of secure element can be supported. Those parameters are
under platform integrator responsibilities.

During initialization, the white_list will be set according to those
parameters.

The discovery_se function will assume a secure element is physically
present according to uicc-present and ese-present values and will add it
to the secure element list. On ese activation, the atr is retrieved to
calculate a command exchange timeout based on the first atr(TB) value.

The se_io will allow to transfer data over SWP. 2 kind of events may appear
after a data is sent over:
- ST21NFCA_EVT_TRANSMIT_DATA when receiving an apdu answer
- ST21NFCA_EVT_WTX_REQUEST when the secure element needs more time than
expected to compute a command. If this timeout expired, a first recovery
tentative consist to send a simple software reset proprietary command.
If this tentative still fail, a second recovery tentative consist to send
a hardware reset proprietary command.
This function is only relevant for eSE like secure element.

This patch also change the way a pipe is referenced. There can be
different pipe connected to the same gate with different host destination
(ex: CONNECTIVITY). In order to keep host information every pipe are
reference with a tuple (gate, host). In order to reduce changes, we are
keeping unchanged the way a gate is addressed on the Terminal Host.
However, this is working because we consider the apdu reader gate is only
present on the eSE slot also the connectivity gate cannot give a reliable
value; it will give the latest stored pipe value.
