Rebased drm-misc-fixes for v5.15-rc5:
- Dropped vc4 patches.
- Compiler fix for vc4.
- Cursor fix for nouveau.
- Fix ttm buffer moves for ampere gpu's by adding minimal acceleration support.
- Small rockchip fixes.
- Fix DT bindings indent for ili9341.
- Fix y030xx067a init sequence to not get a yellow tint.
- Kconfig fix for fb_simple vs simpledrm.
- Assorted nouvaeu memory leaks.
- Fix gbefb when built with COMPILE_TEST.
