Merge branch 'topic-arcpgu-sim' of...

Merge branch 'topic-arcpgu-sim' of https://github.com/foss-for-synopsys-dwc-arc-processors/linux into drm-next

Add support for arcgpu on the sim platform.

* 'topic-arcpgu-sim' of https://github.com/foss-for-synopsys-dwc-arc-processors/linux:
  ARC: [nsimosci] Enable ARC PGU on nSIM OSCI virtual platforms
  ARCv2: [vdk] Enable ARC PGU on HS38 VDK
  drm/arcpgu: Make ARC PGU usable on simulation platforms
