Cover letter [PATCH v4 0/4] ACPI / boot: Don't handle SCI on HW reduced platforms

The series improves handling of invalid IRQs in ACPI glue layer along with preventing setup SCI on HW reduced platforms as it prescribed by the spec.

Patch 1 is just convenient to add to the series.

Patches 2 and 3 make consistent value and variable types for SCI and GSI in ACPI code.

Patch 4 prevents setting up SCI on HW reduced platforms.

The series has been tested on T100TA (HW reduced platform) and on Intel Kabylake.

In v4:
- drop upstreamed patches
- drop patch which belongs to other (future) series
- rework approach to address Rafael's comment
