[ Upstream commit 77006f6edc0e0f58617eb25e53731f78641e820d ]
Currently if the APB or Debounce clocks aren't yet ready to be requested the DW GPIO driver will correctly handle that by deferring the probe procedure, but the error is still printed to the system log. It needlessly pollutes the log since there was no real error but a request to postpone the clock request procedure since the clocks subsystem hasn't been fully initialized yet. Let's fix that by using the dev_err_probe method to print the APB/clock request error status. It will correctly handle the deferred probe situation and print the error if it actually happens.
