[PATCH v2 2/2] net: macb: Allow SGMII only if we are a GEM in mac_validate

This aligns mac_validate with mac_config. In mac_config, SGMII is only
enabled if macb_is_gem. Validate should care if the mac is a gem as
well. This also simplifies the logic now that all gigabit modes depend
on the mac being a GEM.
