drm/xe/xe_ras: Add support to query device memory errors

Browse source

Add initial support to query uncorrectable device memory errors from
system controller. The recovery action for memory errors depends on the
error category. Firmware will set only one error category per response.
Double bit ECC (Error Correcting Code) errors will be handled using Page
offlining in a later patch. Poison and data parity errors are only logged.
Rest of the errors require SBR (Secondary Bus Reset) to recover.
