lynxpoint: Move a bit of generic RCBA into early_pch

Rather than have to repeat this bit in every mainboard.

Also, remove the reset of the RTC power status from here.
    We had done this in TOT for current platforms but did not
    carry it back to emeraldlake2 where this branched from.

If we clear the status here then we don't get an event
    logged later which can be important for the devices that
    do not have a CMOS battery.
