There are two fixes (and several cleanups) that allow to take into
consideration more parameters in ACPI, i.e. bias for GpioInt() and
debounce time for Operation Regions, Events and GpioInt() resources.

The first patch highly depends on Intel pin control driver changes
(they are material for v5.10 [1]), so this is probably not supposed
to be backported (at least right now).

The last patch adds Intel GPIO tree as official one for ACPI GPIO
changes.

Assuming [1] makes v5.10 this series can be sent as PR to Linus
for v5.11 cycle.

Changelog v4:
- extended debounce setting to ACPI events and Operation Regions
- added Ack (Linus)
- added few more cleanup patches, including MAINTAINERS update

Changelog v3:
- dropped upstreamed OF patch
- added debounce fix
