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.
