ALSA: hda: cs35l41: Assert Reset prior to de-asserting in probe and system resume

To ensure we are in a known state, exiting from reset at the point of
probe or in system resume, assert reset before we de-assert it.

Since the BIOS may enter into a pre-boot environment to control the
amps (for example for boot beep), we need to ensure we start from a
known, reset state prior to probe or system resume.
