mb/google/corsola: Add registers reset for ALC5650

The power of codec isn't dropped down when cold reboot on corsola, so
in devbeep sences, the first beep will be loudly due to codec may not
have been initialized. Therefore, we reset codec registers in
configure_alc5645().

BRANCH=corsola
BUG=b:323606238
TEST=Verify devbeep in depthcharge
