phy: ti: gmii-sel: add support for am654x/j721e soc
TI AM654x/J721E SoCs have the same PHY interface selection mechanism for CPSWx subsystem as TI SoCs (AM3/4/5/DRA7), but registers and bit-fields placement is different. This patch adds corresponding support for TI AM654x/J721E SoCs PHY interface selection.
