Currently it shouldn't disrupt state of regulator because during runtime
it may only be only: on (0x3) or off (0x0). Suspend enable in max77686
writes 0x3 to the register which means - always on.
If regulator was disabled before suspend then it has to be enabled
during suspend_enable() call which is exactly what max77686_enable does.
If it was enabled then nothing happens.
