This patch adds support for isochronous out transfers to the HWA.  The
primary changes are:

1.  Add a isoc_pack_desc_urb field to struct wa_seg.  This urb is used
to send the isochronous packet info message to the HWA which describes
the isoc data segment(s) that will be sent as the payload of the
transfer request.

2.  Use the URB iso_frame_desc field to populate the isochronous packet
info message and data segments sent to the HWA.

3.  After the data is sent and transfer result is returned from the
HWA, read the isoc packet status message from the HWA.  The contents of
the isoc packet status message are used to set the iso_frame_desc
status and actual_length fields in the original isoc URB.  This feature
required the addition of a some state tracking variables in struct wahc
so the dti_urb knows what type of packet it expects to receive next.

This function was preventing us from supporting multiple
instances. Get rid of it. Since we support DT boots only,
users can get the control device phandle from the DT node.

omap_get_control_dev() is being deprecated as it doesn't support
multiple instances. As control device is present only from OMAP4
onwards which supports DT only, we use phandles to get the
reference to the control device.

Also get rid of "ti,has-mailbox" property as it is redundant and
we can determine that from whether "ctrl-module" property is present
or not. Get rid of has_mailbox from musb_hdrc_platform_data as well.

As we don't support non-DT boot, we just bail out on probe
if device node is not present.

Add support for new device types and in the process rid of "ti,type"
device tree property. The correct type of device will be determined
from the compatible string instead.

Introduce a compatible string for each device type. At the moment
we support 4 types OTGHS, USB2, PIPE3 (e.g. USB3) and DRA7USB2.

Update DT binding information to reflect these changes.

Also get rid of omap_control_usb3_phy_power(). Just one function
i.e. omap_control_usb_phy_power() will now take care of all PHY types.

This patch adds an implementation for hwahc_op_get_frame_number.  The
request is fulfulled by forwarding it to the lower hcd.  This was done
because the GET_TIME request on the HWA requires sending an URB to the
HWA and waiting for the results which cannot be done in atomic context.

This patch modifies wa_urb_enqueue to return an error and not call the
urb completion routine if it failed to enqueue the urb because the HWA
device is gone.  This prevents a stack overflow due to infinite
submit/complete recursion when unplugging the HWA while connected to a
HID device.

Commit "usb: pci-quirks: refactor AMD quirk to abstract AMD chipset types"
introduced a new AMD chipset type to filter AMD platforms with different
chipsets.

According to a recent thread [1], this patch updates SB800 prefetch routine
in AMD PLL quirk. And make it use the new chipset type to represent SB800
generation.

Value of can_write variable in s3c_hsotg_write_fifo function should be limited
to 512 only for non-periodic endpoints. There was some discrepancy between
comment and code, because comment suggests correct behavior, but in the code
limit was applied to periodic endpoints too. So there is additional check
causing the limitation concerns only non-periodic endpoints.

ffs_do_descs() function call for high speed descriptors. Without this
check it's possible that the module will try dereference incorrect
