This patch adds the parsing of this common DT properties in the u-class "eth_phy_generic", used by default in the associated driver "eth_phy_generic_drv"
This parsing function eth_phy_of_to_plat can be reused by other ethernet phy drivers for this uclass UCLASS_ETH_PHY.

Update eth-phy driver (NEW)

I detect the issue in my stm32/next branch
but I will sent a V3 of the serie with an correction.
