[PATCH 5/7] ASoC: codecs: realtek-soundwire: ignore initial PARITY errors

From: Pierre-Louis Bossart <pierre-louis.bossart at linux.intel.com>

The parity calculation is not reset on a Severe Reset, which leads to
misleading/harmless errors reported on startup. The addition of a
quirk helps filter out such errors while leaving the error checks on
in steady-state.
