The newly added gpio consumer calls cause a build failure in configurations
that fail to include the right header implicitly:

drivers/usb/dwc3/dwc3-xilinx.c: In function 'dwc3_xlnx_init_zynqmp':
drivers/usb/dwc3/dwc3-xilinx.c:207:22: error: implicit declaration of function 'devm_gpiod_get_optional'; did you mean 'devm_clk_get_optional'? [-Werror=implicit-function-declaration]
  207 |         reset_gpio = devm_gpiod_get_optional(dev, "reset", GPIOD_OUT_LOW);
      |                      ^~~~~~~~~~~~~~~~~~~~~~~
      |                      devm_clk_get_optional

Fixes: ca05b38252d7 ("usb: dwc3: xilinx: Add gpio-reset support")

I think it would be better to say what you have done exactly to make sure that 
developers will run it before they send the patch.

Origin patch added this header and I think it should be also removed as the part 
of this patch.
