drm/cirrus: kick out conflicting framebuffers earlier
It appears that grub2 will pass framebuffer info via EFI, this causes the vram reserve to fail, so kick out efifb earlier before cirrus loads. Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=826983 Signed-off-by: Dave Airlie <airlied@redhat.com>
