In order to avoid having potentially ever growing list of variants
that don't support methods implemented in imx6_pcie_reset_phy() and
imx6_setup_phy_mpll(), change logical checks in the to check for SoC's
that _do_ support what they implement. While at it, share the code via
a small helper function.
