Subject: force fb for cirrus and bochs, force drm otherwise
References: bsc#888590, bsc#980750
DRM does not work well with cirrus and bochs (no display) but the framebuffer driver
prevents DRM drivers from loading.
As we need to support cirrus for libvirt and bochs for QEMU, we cannot just remove support for frame-buffer.
