Mario Limonciello 968ab92616 pinctrl: amd: Detect internal GPIO0 debounce handling 
commit 4e5a04be88 ("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 b26cd9325b ("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.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
