A setting of 24 is the correct color depth, but G200ER doesn't seem to be able to use the respective RGB888 color format. Using 24-bit color with forced 32 bpp works around the problem.

But later, commit a0f25a6bb319 ("drm/hisilicon/hibmc: Allow to be built if COMPILE_TEST is enabled") allowed the driver to be built for non-ARM64 when COMPILE_TEST is set but that could lead to unmet direct dependencies and linking errors. Prevent a kconfig warning when MMU is not enabled by making DRM_HISI_HIBMC depend on MMU.
