Add support for Current Limit Extension (CLX) feature found on a few A8x
GPUs. This feature is required to limit the peak current consumption to
avoid HW spec violation on GX/MX rails.

Add the necessary HFI interface support to pass the recommended CLX and
IFF/PCLX limits tables to the GMU. And enable this feature on both A840
and X285 GPU by adding the repective configurations to the gpu catalog.
