mfd: twl4030-power: Use 'ti,system-power-controller' as alternative way to support system power off
ti,system-power-controller is more or less the standard way of indicating that the PMIC is the system wide power controller and hence may be used to switch off the system. Almost ALL TI PMIC drivers and many Maxim PMIC drivers follow the same style. So support 'ti,system-power-controller' in addition to the usual 'ti,use_poweroff' to indicate that the PMIC instance has control for switching off the system.
