Add support for GSC in XeHP SDV (Intel(R) dGPU without display).
 
XeHP SDV GSC controller uses the same hardware settings as DG1, but uses
polling instead of interrupts and runs the firmware in slow pace due to
hardware limitations.

This series should be applied over "Add driver for GSC controller"
patch series.

Greg KH, please review and ACK the MEI patches.
We are pushing all through gfx tree as the device belongs there.

  drm/i915/gsc: add GSC XeHP SDV platform definition
  mei: gsc: wait for reset thread on stop
  mei: extend timeouts on slow devices.
