regmap: merge regmap_update_bits_async() into macro

Browse source 
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_async() into macro
by using regmap_update_bits_base().
