This patch adds support to read/write SLIMbus value elements. Currently it only supports byte read/write. Adding this support in regmap would give codec drivers more flexibility when there are more than 2 control interfaces like SLIMbus, i2c. Without this patch each codec driver has to directly call SLIMbus value element apis, and this could would get messy once we want to add i2c interface to it.
