net: phy: bcm7xxx: utilize PHY revision in config_init

Browse source 
Now that the GENET and SF2 drivers have been updated to communicate us
what is the revision of the BCM7xxx integrated PHY, utilize that
information in the config_init() callback to call into the appropriate
workaround function based on our revision.

While at it, we also print the revision and patch level to help debug
new chips.
