Attempts to build the sun4i drm code on various architectures using gcc 11.x or older fails with ERROR: modpost: "__udivdi3" [drivers/gpu/drm/sun4i/sun4i-drm-hdmi.ko] undefined! This is due to commit 358e76fd613a ("drm/sun4i: hdmi: Consolidate atomic_check and mode_valid") which introduces a constant 64-bit divide operation. Some compilers / compiler versions fail to translate this operation into fixed code. Manual exclusion lists such as "Only build test this code on this subset of architectures" or "Do not test this code on this set of architectures" do not scale. Remove COMPILE_TEST support for the suni4 drm driver instead to ensure that test builds are only performed on supported architectures.
