net: bcmgenet: add support for new GENET PHY revision scheme

Browse source

Starting with GPHY revision G0, the GENET register layout has changed to
use the same numbering scheme as the Starfighter 2 switch. This means
that GPHY major revision is in bits 15:12, minor in bits 11:8 and patch
level is in bits 7:4.

Introduce a small heuristic which checks for the old scheme first, tests
for the new scheme and finally attempts to catch reserved values and
aborts.
