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].

V6: *Fix memory leak. *If EINJv2 initialization failed, EINJv1 will still work, and probe function will continue with disabled EINJv2. V7: *Update component array to take 128-bit values to match ACPI specs. *Enable Vendor EINJv2 injections *Moved component array parsing and validating to a separate function to improve readability.
