This patch is causing crashes of Manor Lords on my Navi 21 on the 6.8.9
stable kernel. It leads to an assertion failure in wine:
File: ../src-wine/dlls/winevulkan/loader_thunks.c
Line: 3621
Expression "!status && vkEndCommandBuffer""
This happens both with radv and amdvlk. It starts happening on v6.8.8
with this patch. The previous patch (drm/amdgpu/sdma5.2: use legacy HDP
flush for SDMA2/3) is fine.

HDP Flush request bit can be kept unique per AID, and doesn't need to be
unique SOC-wide. Assign only bits 10-13 for SDMA v4.4.2.
