regulator: act8945a-regulator: Implement PM functionalities
The regulator supports a dedicated suspend mode. Implement the appropriate ->set_suspend_xx() hooks, add support for ->set_mode(), and provide basic PM ops functionalities to setup the regulator in a suspend state when the system is entering suspend. Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com> [claudiu.beznea@microchip.com: remove shutdown function, use dev_pm_ops, fix checkpatch warning, adapt commit message, add LDO modes support, move modes constants to active-semi,8945a-regulator.h, remove rdevs from struct act8945a_pmic, add op_mode to act8945a_pmic] Signed-off-by: Claudiu Beznea <claudiu.beznea@microchip.com> Signed-off-by: Mark Brown <broonie@kernel.org>
