drm: flip cirrus driver status to "obsolete".
Also update Kconfig help text, explaining things: Cirrus is obsolete, the hardware was designed in the 90ies and can't keep up with todays needs. More background: https://www.kraxel.org/blog/2014/10/qemu-using-cirrus-considered-harmful/ Better alternatives are: - stdvga (DRM_BOCHS, qemu -vga std, default in qemu 2.2+) - qxl (DRM_QXL, qemu -vga qxl, works best with spice) - virtio (VIRTIO_GPU), qemu -vga virtio) Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
