regmap: add regmap_update_bits_base()
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 adds new regmap_update_bits_base() which is feature
merged function. Above functions can be merged into it by macro.
