Subject: [PATCH v6 00/11] drm/amdgpu: preparation patchs for the use all SDMA instances series

This series is a subset of the "use all SDMA instances" series.
It starts at the first modified patch and ends at the last patch
before the drm/ttm patch that got merged through drm-misc-next.

The main changes from v5 are:
  * split "drm/amdgpu: remove AMDGPU_GTT_NUM_TRANSFER_WINDOWS" into
    3 patches: one modifying vce, one dealing with ttm and one removing
    AMDGPU_GTT_NUM_TRANSFER_WINDOWS.
  * dropped "drm/amdgpu: use larger gart window when possible".

v5:

v3 of the full series:
  https://lists.freedesktop.org/archives/dri-devel/2025-November/537830.html
