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.
