ASoC: wm5110: Fix PGA clear when disabling DRE
We don't want to use a bypassed write in wm5110_clear_pga_volume, we might disable the DRE whilst the CODEC is powered down. A normal regmap_write will always go to the hardware (when not on cache_only) even if the written value matches the cache. As using a normal write will still achieve the desired behaviour of bring the cache and hardware in sync, this patch updates the function to use a normal write, which avoids issues when the CODEC is powered down.
