nyan: force shutdown uses PMIC THERM instead.
Add a new pin PMIC_THERM_L (PA1) since AP_RESET_L (PA15) is removed.
To force shutdown, drive PMIC_THERM_L to low (default high) for 32us.
Also rename set_pmic_pwrok() -> set_pmic_pwron(). And add a debounce time
for PMIC_PWRON_L pin.
BUG=chrome-os-partner:24206
BRANCH=nyan
TEST=Verified on the frank's rework board.
'power off' shutdowns the AP immediately.
'reboot' reboots the EC and resets the AP as well.
'sysjump RW' still keeps AP alive.
