bcm7445_config_init() was working around non-production version of the PHY HW block, so just remove it entirely. bcm7xxx_28nm_afe_config_init() was running for all PHY revisions greater than B0, but this workaround sequence is really specific to the B0 PHY revision, so rename the function accordingly and update the GPHY macro to use the generic config_init callback.
