Along with the transition to regmap for managing the cached parameter reads, the caps overwrite was also moved to regmap cache. The cache change itself works, but it still tries to write the non-existing verb (the HDA parameter is read-only) wrongly. It's harmless in most cases, but some chips are picky and may result in the codec communication stall. This patch avoids it just by adding the missing flag check in reg_write ops.
