Use a single reset_control_reset() instead of assert/deasset couple in order to make code cleaner a tad. Note that the reset_control_reset() uses 1 microsecond delay instead of 2 that was used previously, but this shouldn't matter. In addition don't ignore potential error of the reset control by emitting a noisy warning if it fails, which shouldn't ever happen in practice.
