regmap: mdio: make it depend on PHYLIB

MDIO-based regmap is the last user of config symbol MDIO_BUS.
MDIO access needs a MII bus, which requires PHYLIB for the provider part.
Therefore make REGMAP_MDIO depend on PHYLIB, what allows to remove
config symbol MDIO_BUS in a follow-up patch.

Note: After c5a219395b4e ("regmap: Move selecting for REGMAP_MDIO and
      REGMAP_IRQ") switching to "depends on" should be fine, w/o risk
      of a circular dependency.
