The current output code only supports connection to drm panels.
First simplify the drm panel code, and then add support for external drm
bridges.

In order to support multiple outputs we need to move the output mode
selection to the CRTC object, so that the output validity check can be
done against the drm_atomic_state.
If the connectors selected by a specific mode setting are requiring
incompatible bus format the atomic operation is aborted (->atomic_check()
returns -EINVAL).
In order to implement that, we need to define our own CRTC state and
overload default ->reset(), ->atomic_duplicate_state() and
->atomic_destroy_state() functions.

The ->dpms field is no longer used and can be removed.
The same goes for the dummy ->mode_fixup() implementation which always
returns true.

The hlcdc IP keep the pixel stream in raw RGB mode, and does not provide
any specific connector. Since DRM_MODE_CONNECTOR_RAW_RGB does not exist,
use DRM_MODE_CONNECTOR_Unknown.

Done with coccinelle for the most part. However, it thinks '...' is
part of the semantic patch, so I put an 'int DOTDOTDOT' placeholder
in its place and got rid of it with sed afterwards.

The Atmel HLCDC (HLCD Controller) IP available on some Atmel SoCs (i.e.
at91sam9n12, at91sam9x5 family or sama5d3 family) provides a display
controller device.
This display controller supports at least one primary plane and might
provide several overlays and an hardware cursor depending on the IP
version.
At the moment, this driver only implements an RGB connector to interface
with LCD panels, but support for other kind of external devices might be
added later.
