[PATCH v6 0/3] Introduce Xe Correctable Error Handling

[Raag Jadav <raag.jadav@intel.com>]

This series builds on top of system controller series[1] and adds initial
support for correctable error handling in xe. This serves as a foundation
for RAS infrastructure and will be further extended to facilitate other
RAS features.
