RTL822x cannot access MDIO_MMD_VEND2 via MII_MMD_CTRL/MII_MMD_DATA. A
mapping to use paged access needs to be used instead. All other MMD
devices can be accessed as usual.

Implement phy_read_mmd and phy_write_mmd using paged access for
MDIO_MMD_VEND2 in Clause-22 mode instead of relying on
MII_MMD_CTRL/MII_MMD_DATA. This allows eg. rtl822x_config_aneg to work
as expected in case the MDIO bus doesn't support Clause-45 access.
