Subject: [PATCH v2 0/9] Enable EINJv2 support

The goal of this update is to allow the driver to simultaneously
support EINJ and EINJv2. The implementation follows the approved
ACPI specs(1)(2) that enables the driver to discover system
capabilities through GET_ERROR_TYPE.

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

(2) https://bugzilla.tianocore.org/attachment.cgi?id=1521
(3) https://github.com/acpica/acpica/pull/977

Note: This revision includes an update on patch 5/9 to avoid
ambiguity between EINJv1 and EINJv2 error types. Also, it includes
an additional patch to fix sparse warnings triggered by test robot.
