This patch adds support for RX and TX DMA via the DMA API,
this is only supported when the KS8842 is accessed via timberdale.

There is no support for DMA on the generic bus interface it self,
a state machine inside the FPGA is handling RX and TX transfers to/from
buffers in the FPGA. The host CPU can do DMA to and from these buffers.

The FPGA has to handle the RX interrupts, so these must be enabled in
the ks8842 but not in the FPGA. The driver must not disable the RX interrupt
that would mean that the data transfers into the FPGA buffers would stop.

The host shall not enable TX interrupts since TX is handled by the FPGA,
the host is notified by DMA callbacks when transfers are finished.

Which DMA channels to use are added as parameters in the platform data struct.

For Simple Ethernet frames (802.2 and 802.3) the GMAC Core
never strips pad and fcs. This means the ACS has no effect
on IPv4/6 frames.
The FL bits, in the RDES0, include the FCS so the driver
has to remove it in SW.
For 802.3 frame format with LLC or LLC-SNAP, when set the ACS
bit, the HW strips both PAD and FCS.
The FL bits, in the RDES0, actually represents the frame length
already stripped.
This patch fixes this logic within the device driver that
erroneously removed 4byte from 802.3 frames already stripped
corrupting the payload.

The driver erroneously sets the tmrate to zero when the
TMU initialisation fails. This actually generates problems
while using the dual GMAC configuration.

With this patch, enabling both the dual gmac and the timer
optimisation, the first interface opened will use the tmu
channel 2, the second one won't be able to use the timer but
will continue to work without mitigating the interrupts by
using the external timer (i.e. TMU channel 2).

Add addr_assign_type to struct net_device and expose it via sysfs.
This new attribute has the purpose of giving user-space the ability to
distinguish between different assignment types of MAC addresses.

For example user-space can treat NICs with randomly generated MAC
addresses differently than NICs that have permanent (locally assigned)
MAC addresses.
For the former udev could write a persistent net rule by matching the
device path instead of the MAC address.
There's also the case of devices that 'steal' MAC addresses from slave
devices. In which it is also be beneficial for user-space to be aware
of the fact.

This patch also introduces a helper function to assist adoption of
drivers that generate MAC addresses randomly.
