PATCH 1/2 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.

PATCH 2/2 regulator: Use tps65912_get_voltage for both DCDCs and LDOs

Now tps65912_get_voltage_dcdc and tps65912_get_voltage_ldo has exactly the same implementation. We can merge them to tps65912_get_voltage function.

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.

Applied both, thanks.
