phy: phy-rockchip-samsung-hdptx: Don't use dt aliases to determine phy-id

The phy needs to know its identity in the system (phy0 or phy1 on rk3588)
for some actions and the driver currently contains code abusing of_alias
for that.

Devicetree aliases are always optional and should not be used for core
device functionality, so instead keep a list of phys on a soc in the
of_device_data and find the phy-id by comparing against the mapped
register-base.
