Subject: ASoC: rt5651: Fix regcache sync errors on resume

From: Hans de Goede <hdegoede@redhat.com>

commit 2d30e9494f1ea320aaaad0cff9ddd92c87eac355 upstream.

The ALC5651 does not like multi-write accesses, avoid them. This fixes:

rt5651 i2c-10EC5651:00: Unable to sync registers 0x27-0x28. -121

Errors on resume (and all registers after the registers in the error not
being synced).
