    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.
