regmap: merge regmap_update_bits_check_async() into macro
Current regmap has many similar update functions like below,
but the difference is very few.
regmap_update_bits()
regmap_update_bits_async()
regmap_update_bits_check()
regmap_update_bits_check_async()
Furthermore, we can add *force* write option too in the future.
This patch merges regmap_update_bits_check_async() into macro
by using regmap_update_bits_base().
