[PATCH v2 4/5] regulator: rk808: Support apply_bit for rk808_set_suspend_voltage_range

[Alex Bee]

rk808_set_suspend_voltage_range currently does not account the existence of
apply_bit/apply_reg.

This adds support for those in same way it is done in
regulator_set_voltage_sel_regmap and is required for the upcoming RK816
support
