Subject: [PATCH v2 2/4] ASoC: cs42l42: Remove redundant writes to RS_PLUG/RS_UNPLUG masks

The RS_PLUG and RS_UNPLUG interrupt masks are always written as 1 so
those writes are redundant and can be deleted.

This makes it completely clear in the code that only the TS_PLUG and
TS_UNPLUG masks are being changed.
