15b6412bad drm: rcar-du: Rely on the default ->best_encoder() behavior
All outputs have a 1:1 relationship between connectors and encoders,
and the driver is relying on the atomic helpers: we can drop the custom
->best_encoder() implementations and let the core call
drm_atomic_helper_best_encoder() for us.

c1d4b38c93 drm: rcar-du: Perform initialization/cleanup at probe/remove time
The drm driver .load() operation is prone to race conditions as it
initializes the driver after registering the device nodes. Its usage is
deprecated, inline it in the probe function and call drm_dev_alloc() and
drm_dev_register() explicitly.

For consistency inline the .unload() handler in the remove function as
well.

f348323240 drm: rcar-du: Switch connector DPMS to atomic helpers
The atomic connector DPMS helper implements the connector DPMS operation
using atomic commit, removing the need for DPMS helper operations on
CRTCs and encoders.

3e8da87d0c drm: rcar-du: Wire up atomic state object scaffolding
Hook up the default .reset(), .atomic_duplicate_state() and
.atomic_free_state() helpers to ensure that state objects are properly
created and destroyed, and call drm_mode_config_reset() at init time to
create the initial state objects.

Framebuffer reference count also gets maintained automatically by the
transitional helpers except for the legacy page flip operation. Maintain
it explicitly there.

8b37c32647 drm: rcar-du: Don't set connector->encoder at init time
The drm_connector encoder field points to the encoder driving the
connector. No such association exists at init time, as all pipelines are
disabled. Don't set the field.

4b96b70cfa drm: rcar-du: Replace direct DRM encoder access with cast macro
Add a new macro to downcast an rcar_du_encoder pointer to a drm_encoder
pointer and use it. This prepares for the replacement of the
rcar_drm_encoder encoder field with a drm_slave_encoder.

f9b0e251df drm: make mode_valid callback optional
Many drm connectors do not need mode validation.
The patch makes this callback optional and removes dumb implementations.

v2: Rebase:
- imx move to a shared (but still dummy) ->mode_valid implementation.
- probe helpers have been extracted to drm_probe_helper.c
