drivers: phy: add drivers for PHYs supported by legacy MDIO driver

The legacy MDIO/PHY driver integrated into the Xilinx GEM device
driver supported two PHY families: the Marvell Alaska 88E1xxx
series PHYs and the TI DP83822 which is a pin- and register
compatible drop-in replacement of the TI TLK105, which is
therefore also supported by the same driver. These two PHY families
are now provided as separate drivers implemented against the
standard PHY driver APIs, therefore also enabling their use with
MACs other than the GEM.
