[PATCH 0/2] drm/xe: GSC proxy support

[Daniele Ceraolo Spurio]

The GSC uC needs to communicate with the CSME to perform certain
operations. Since the GSC can't perform this communication directly on
platforms where it is integrated in GT, the graphics driver needs to
transfer the messages from GSC to CSME and back.
Since the CSME is controlled by the mei driver, we need to use a mei
component to communicate with it.
