Michal Wajdeczko 13295bd887 drm/i915/guc: Don't read SOFT_SCRATCH(15) on MMIO error ... SOFT_SCRATCH(15) is used by GuC for sending MMIO GuC events to host and those events are now handled by intel_guc_to_host_event_handler_mmio(). We should not try to read it on MMIO action error as 1) we may be using different set of registers for GuC MMIO communication, and 2) GuC may use CTB mechanism for sending events to host. While here, upgrade error message to DRM_ERROR.
