However, ARL requires a newer version of it. So add differentiate of the PCI ids for ARL from MTL and create ARL as a sub-platform of MTL. That way, all the existing workarounds and such still treat ARL as MTL exactly as before. However, now the GSC code can check for ARL and do an extra version check on the firmware before committing to it. Also, the version extraction code has various ways of failing but the return code was being ignore and so the firmware load would attempt to continue anyway. Fix that by propagating the return code to the next level out.

Therefore, if GSC fails to load there is no need to try again because the HW is stuck in the error state and the submission to load the FW would just hang the GSCCS. Note that, due to wa_14015076503, on MTL the GuC escalates all GSCCS hangs to full GT resets, which would trigger a new attempt to load the GSC FW in the post-reset HW re-init; this issue is also fixed by not attempting to load the GSC FW after an error.
