[PATCH v3 05/22] i2c: tegra: Use reset_control_reset()

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.
