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.
