  Add initial GSC support for DG1 and DG2.
Create mei-gscfi auxiliary device and add
support for device created by Xe to the mei-gsc driver.

This series intended to be merged into Xe tree,
the only patch that touches char-misc is addition
of id and alias in mei-gsc.

V3: Review comments addressed:
    - xe_heci_gsc_init mover earlier
    - part of init flow moved to dedicated functions
    - KDoc fix

V2: Added heci_ to struct and APIs
    heci_gsc moved under xe_device as GSC is not under GT
