camera: sec_m5mo: Introduce low-power flash mode

This new low-power flash mode is an emulated flash mode that only exists in the kernel (it is not in the HAL). When battery is at 35% or lower, low-power flash is automatically enabled and sets the flash LEDs to low power (rather than the regular high-power mode).

Low-power flash fixes the hard shutdowns that occur while taking pictures with flash on low battery.
