drm/amdgpu: disable vga render in dce hw_init
This got dropped accidently with the fb location changes, but for some reason, this doesn't seem to cause an issue on all cards which is why I never saw it despite extensive testing. I suspect it may only be an issue on systems with a legacy sbios that enables vga. Tested-by: Andres Rodriguez <andresx7@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
