mb/google/asurada: Implement enable_regulator and regulator_is_enabled
SD Card driver needs to access two regulators - MT6360_LDO5 and
MT6360_LDO3. These two regulators are disabled by default.
Two APIs are implemented:
- mainboard_enable_regulator: Configure the regulator as enabled/disabled.
- mainboard_regulator_is_enabled: Query if the regulator is enabled.
