usb: dwc3: Fix remove function if there is no ulpi_reset gpio
As ulpi_reset gpio is now optional, we need to check it when doing
the 'dwc3_generic_remove' function. Check if it is declared before
accessing the ulpi_reset.
Fixes: 237d1f60b1d ("usb: dwc3: Use the devm_gpiod_get_optional()
API for reset gpio")
