[PATCH 8/9] drm/amdgpu: enable userqueue support for GFX12

From: Somalapuram Amaranath <Amaranath.Somalapuram at amd.com>

This patch enables Usermode queue support across GFX, Compute
and SDMA IPs on GFX12/SDMA7. It typically reuses Navi3X userqueue
IP functions to create and destroy MQDs.

v2: rebase on proposed changes (Alex)
