drm/xe: Introduce xe_pcode component.

Rodrigo Vivi requested to merge rodrigovivi/drm-xe:xe_pcode into xe

The goal is that this component will be solely responsible for any communication to PCODE. It will export functions to perform specific actions rather than exposing generic read and write operations.

This one starts with the PCODE min freq qos setup table needed for the gen12 integrated parts.

There's still a lot to be done here in this component:

  • documentation
  • locks
  • init done timeout for dgfx
  • hw metrics
  • display operations
