pinctrl: amd: Detect internal GPIO0 debounce handling

pinctrl: amd: Detect internal GPIO0 debounce handling

commit 968ab9261627fa305307e3935ca1a32fcddd36cb upstream.

commit 4e5a04be88fe ("pinctrl: amd: disable and mask interrupts on probe")
had a mistake in loop iteration 63 that it would clear offset 0xFC instead
of 0x100.  Offset 0xFC is actually `WAKE_INT_MASTER_REG`.  This was
clearing bits 13 and 15 from the register which significantly changed the
expected handling for some platforms for GPIO0.

commit b26cd9325be4 ("pinctrl: amd: Disable and mask interrupts on resume")
actually fixed this bug, but lead to regressions on Lenovo Z13 and some
other systems.  This is because there was no handling in the driver for bit
15 debounce behavior.

Quoting a public BKDG:
```
EnWinBlueBtn. Read-write. Reset: 0. 0=GPIO0 detect debounced power button;
Power button override is 4 seconds. 1=GPIO0 detect debounced power button
in S3/S5/S0i3, and detect "pressed less than 2 seconds" and "pressed 2~10
seconds" in S0; Power button override is 10 seconds
```

Cross referencing the same master register in Windows it's obvious that
Windows doesn't use debounce values in this configuration.  So align the
Linux driver to do this as well.  This fixes wake on lid when
WAKE_INT_MASTER_REG is properly programmed.
