ASoC: cs4270: Set auto-increment bit for register writes

[ Upstream commit f0f2338a9cfaf71db895fa989ea7234e8a9b471d ]

The CS4270 does not by default increment the register address on
consecutive writes. During normal operation it doesn't matter as all
register accesses are done individually. At resume time after suspend,
however, the regcache code gathers the biggest possible block of
registers to sync and sends them one on one go.

To fix this, set the INCR bit in all cases.
