In the probe path, dev_err() can be replaced with dev_err_probe()
which will check if error code is -EPROBE_DEFER and prints the
error name. It also sets the defer probe reason which can be
checked later through debugfs.

The error handling of devm_reset_control_get_by_index() could probably
be replaced with dev_err_probe() aswell.
