Remove the obsolete fb unreferencing system that is no longer used
since we've transitioned to atomic modeset.

We no longer require a private armada_plane structure, so eliminate
it, and use the drm_plane structure directly.

The framebuffer base address and toggling mode needs to be updated
when the interlaced flag for mode changes is updated. Arrange to
reprogram these parameters when only the mode has changed.

Write out the plane updates after the dumb frame has completed, but
just before the blank period. This allows all the plane updates to
be performed in a flicker-free non-tearing manner.

Switch the overlay plane away from the transitional helpers and legacy
methods, and use atomic helpers instead to implement the legacy
set_plane ioctl methods.

Switch the primary plane away from the transitional helpers, and
use the atomic helpers instead to implement the legacy set_plane
ioctl call for this plane.

Switch the legacy set_config() method to use the atomic modeset
helper, which allows us to get rid of the legacy dpms, prepare,
commit, mode_set, mode_set_base and disable helper methods.

Implement the atomic_enable()/atomic_disable() methods used by the
atomic modeset helpers. atomic_disable() will need some transitional
code during conversion to ensure proper ordering is maintained.

Explicitly pass in the desired enable/disable state into
armada_drm_crtc_update() rather than having it use the DPMS state
stored in our crtc structure.

Push responsibility for managing the clock during DPMS down into the
variant backend, rather than the CRTC layer having knowledge of its

Prepare handling for atomic modeset CRTC events. Currently, using the
transition helpers, CRTC events do not exist, but once we switch to
proper atomic modeset, they have to be handled.
We queue an event for the next vblank in two places:
- armada_drm_crtc_atomic_flush() provided we aren't doing an
atomic modeset.
- armada_drm_crtc_commit() if we are committing a modeset.
This ensures that the event is sent at the correct time (after all
updates have been written to the hardware and after the following
vblank.)

Rather than writing all bits of SPU_ADV_REG on modeset, only write
what we need to change, and initialise the register in the variant
initialisation.

Update debug to use KMS level, and print the mode using the standard
format for mode lines, but print the adjusted CRTC parameters as
that's what we will be programming for.

For atomic modeset, we need to set the sync signal polarities from the
CRTC state structure rather than the legacy mode structure stored in
CRTC. In any case, we should update this from our mode_set_nofb()
method, rather than the commit() method. Move it there, and ensure
that armada_drm_crtc_update() will not overwrite these bits.

Push the interlaced frame calculation down into armada_drm_plane_calc()
which needs to apply the same correction for both the overlay and
primary planes.

Provide the framebuffer pitches from armada_drm_plane_calc_addrs() as
well as the base addresses for each plane. Since this is now about
more than just addresses, rename to armada_drm_plane_calc().

armada_drm_plane_calc_addrs() gets all its information from the plane
state, so it makes sense to pass the plane state pointer down into this
function, rather than extracting the information in identical ways,
sometimes a couple of layers up.

Move the armada_drm_mode_config_funcs to armada_drv.c, since this now
has less to do with FBs than it does with general mode configuration.
In doing so, we need to make armada_fb_create() visible to armada_drv.c,
which reveals a function name clash with armada_fbdev.c. Rename the
version in armada_fbdev.c.

Use the DRM standard plane properties for specifying the YUV
colour encoding parameter. Our colour range is fixed at limited
range.
Since we are transitioning to atomic modeset, we need to explicitly
add handling of these properties to our atomic_set_property() method,
but once the transition is complete, these will be removed.

Remove the unused CRTC colourspace properties - userspace does not make
use of these. In any case, these are not a property of the CRTC, since
they demonstrably only affect the video (overlay) plane, irrespective
of the format of the graphics (primary) plane.

Move the overlay plane colorkey properties into the plane state,
