Provide minimal regulator support. Only supported operations are enabling and disabling regulators. Association of devices with their regulators is limited to devicetree only. If regulator support is disabled the API expands to static inline stubs so consumers can still use the API. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
