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().

* regmap_update_bits_check_async: Perform a read/modify/write cycle on the

* @map: Register map to update
* @reg: Register to update
* @mask: Bitmask to change
* @val: New value for bitmask
* @change: Boolean indicating if a write was done
*
* With most buses the read must be done synchronously so this is most
* useful for devices with a cache which do not need to interact with
* the hardware to determine the current register value.
*
* Returns zero for success, a negative number on error.
