[PATCH 12/12] drm/cirrus: advertise DRIVER_ATOMIC

[Varad Gautam]

From: Varad Gautam <varad.gautam at collabora.com>

allow userspace to use atomic ioctls.

we now pass the following tests when running with cirrus.bpp=32:
igt/kms_atomic_transition:
    plane-all-transition
    plane-use-after-nonblocking-unbind
    plane-all-modeset-transition
    plane-toggle-modeset-transition
    1x-modeset-transitions
    1x-modeset-transitions-nonblocking
igt/kms_atomic:
    plane_primary_legacy
    test_only
    plane_cursor_legacy
    plane_invalid_params
    crtc_invalid_params
igt/kms_setmode
igt/kms_rmfb
drm-tests/atomictest:
    disable_primary
    fullscreen_video
    overlay_pageflip
    primary_pageflip
    video_overlay
