usb: dwc3: xilinx: use reset_control_reset() in versal init

Browse source

Replace reset_control_assert()/deassert() with reset_control_reset().
For dwc3-xilinx, reset_control_reset() routes via the zynqmp reset
driver and uses PM_RESET_ACTION_PULSE, which performs assert and
deassert in firmware. This results in a single SMC call issuing a
reset pulse and taking the IP out of reset.
