regulator: Implement tps65912_list_voltage to be shared by both DCDCs and LDOs
Merge tps65912_list_voltage_dcdc and tps65912_list_voltage_ldo to tps65912_list_voltage. This change does not add too much complexity in tps65912_list_voltage function. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
