regulator: core: Allow specify apply_[reg|bit] for regmap based voltage_sel operations
Some DVM regulators needs to update apply_bit after setting vsel_reg to
initiate voltage change on the output. This patch adds apply_reg and
apply_bit to struct regulator_desc and update
regulator_set_voltage_sel_regmap() to set apply_bit of apply_reg when
apply_bit is set.
