This commit adds support for the GENETv5 implementation.
The GENETv5 reports a major version of 6 instead of 5 so compensate
for this when verifying the configuration of the driver. Also the
EPHY revision is now contained in the MDIO registers of the PHY so
the EPHY revision of 0 in GENET_VER_FMT is expected for GENETv5.

This commit changes the ioctl handling behavior to return the
EOPNOTSUPP error code instead of the EINVAL error code when an
unknown ioctl command value is detected.
It also removes some redundant parsing of the ioctl command value
and allows the SIOCSHWTSTAMP value to be handled.

Also, remove the unnecessary computation when updating the consumer

Since the DMA interrupt status is latched and the DMA servicing can be
polled, it is a good idea to clear the latched status of a DMA interrupt
before performing the service that would be invoked by the interrupt.
This prevents old status from causing spurious interrupts when the
interrupt is unmasked at a later time.

So far were were allocating struct bgmac in 3 places: platform code,

bgmac_enet_probe:
1) Requiring early-filled struct bgmac
2) Calling alloc_etherdev on its own in order to use netdev_priv later
This solution got few drawbacks:
1) Was duplicating allocating code
2) Required copying early-filled struct
3) Resulted in platform/bcma code having access only to unused struct
Solve this situation by simply extracting some probe code into the new
