The Cadence GEM is based on the MACB Ethernet controller but has a few
small changes with regards to register and bitfield placement. This
patch detects the presence of a GEM by reading the module ID register
and setting a flag appropriately.
This handles the new HW address, USRIO and hash register base register
locations in GEM.
v3: - convert to macb_is_gem() inline rather than storing a boolean
flag
- handle rx_overrun stats for gem

Move the Atmel driver into drivers/net/ethernet/cadence/ and
make the necessary Kconfig and Makefile changes.
