pinctrl: amd: Clear `Less2secSts` and `Less10secSts` for GPIO0

Systems that don't program GPIO0 through _AEI may still control
the power button via this GPIO.  When the GPIO master controller
register has bit 15 configured for `EnWinBlueBtn` this will cause
GPIO 0 to behave differently. If the user presses the button for
less than 2 seconds or less than 10 seconds then it is expected
that interrupt status must be cleared by the GPIO driver.

Add a notification chain for the ACPI power button so that
when a power button is pressed it will explicitly clear these
bits.
