Subject: [RFC PATCH v2 0/8] Enable EINJv2 support

This patch set intends to enable EINJv2 support. The goal of this
update is to allow the driver to simultaneously support EINJ and EINJv2.
The implementation follows a proposed ACPI specs(1)(2) that enables the
driver to discover system capabilities through GET_ERROR_TYPE.

Note: this revision includes new updates from the last review, where
some changes remove redundant code as well as converting decimal
values to hex for consistency purposes. This revision also includes
CXL error injection updates.

Note: The first two ACPICA patches are to be dropped once merged in
ACPICA project(3).
