net: pcs: xpcs: add support for NXP SJA1110
The NXP SJA1110 switch integrates its own, non-Synopsys PMA, but it manages it through the register space of the XPCS itself, in a small register window inside MDIO_MMD_VEND2 from address 0x8030 to 0x806e. This coincides with where the registers for the default Synopsys PMA are, but the register definitions are of course not the same. This situation is an odd hardware quirk, but the simplest way to manage it is to drive the SJA1110's PMA from within the XPCS driver.
