When an interrupt is received for correctable errors indicating that error counter has crossed its threshold, read the current counter value and deliver a drm-ras error-event to userspace for each affected component. Also send drm-ras error-event to userspace for uncorrectable errors on receiving an AER. To avoid sending duplicate events when the same component appears multiple times in the response, Send the error-event once per component.

Similar to threshold crossed case, we should probably have a BUILD_BUG_ON() against XE_RAS_NUM_ERROR_ARR. Reviewed-by: Raag Jadav <raag.jadav@intel.com>
