ARM64: zynqmp: Add support for USB ulpi phy reset via mode pins

Mode pins can be used as output for reset. Xilinx boards are using
this feature as additional way how to reset USB phys and also others
chips on the boards.
Mode1 is used on all these boards for this feature.
Let SPL toggle reset on this pin by default.
