Subject: [PATCH v5 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).

(1) https://github.com/tianocore/edk2/issues/9449
(2) https://github.com/tianocore/edk2/issues/9017
(3) https://github.com/acpica/acpica/pull/977

Note: This revision includes a minor change to the user interface,
where users no longer input component array size, instead the size
of the array is parsed by counting lines from user input.
