regulator: wm8400: Get rid of wm8400_block_read/wm8400_set_bits functions
The only user of wm8400_block_read/wm8400_set_bits functions is the
wm8400 regulator driver. At the context of all the callers, we can
use regmap_bulk_read/regmap_update_bits directly.
Thus remove wm8400_block_read/wm8400_set_bits functions.
