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() into macro by using regmap_update_bits_base().
