PS4, Line 27: 	poweroff();
> Wait, where did the rest of this function go? Who is doing the delay and the elog entry now? (If this function does nothing more than `poweroff()`, it doesn't need to exist, the caller could just call `poweroff()` directly.)

I will add delay and elog in this same function alongwith CL that introduces PLATFORM_HAS_LOW_BATTERY_INDICATOR Kconfig, therefore, this function will grow to support platform with PLATFORM_HAS_LOW_BATTERY_INDICATOR Kconfig enabled. This is just a skeleton for now
