The Baikal-T1 APB bus driver correctly handles the deferred probe
situation, but still pollutes the system log with a misleading error
message. Let's fix that by using the dev_err_probe() method to print the
log message in case of the clocks/resets request errors.

Changelog v2:
- Use the dev_err_probe() return value as the return status of the
  corresponding method. (@Philipp)
