Power_x86: Correct the debounce delay for SYS_RESET_L signal
RVP uses MAX6818 to digitize the apreset physical button.
The EC SYS_RESET_L is connected to input of the digitizer.
From MAX6818 Data sheet, range of 'Debounce Duration' is
Minimum - 20 ms, Typical - 40 ms, Maximum - 80 ms.
Hence, implemented an override function to wait for an appropriate delay.
BUG=b:153128296
BRANCH=none
TEST=manually tested on TGLRVP, aprset EC console command triggers
warm boot
