The drm_bridge_funcs.atomic_reset callback and its
drm_atomic_helper_bridge_reset() helper are deprecated.

Switch to the atomic_create_state callback and its
drm_atomic_helper_bridge_create_state() counterpart.

This driver calls drm_of_find_panel_or_bridge() with a NULL pointer in the
@panel parameter, thus using a reduced feature set of that function.
Replace this call with the simpler of_drm_get_bridge_by_endpoint().

Since of_drm_get_bridge_by_endpoint() increases the refcount of the
returned bridge, ensure it is put on removal. To achieve this, instead of
adding an explicit drm_bridge_put(), migrate to the bridge::next_bridge
pointer which is automatically put when the bridge is eventually freed.

The zynqmp-dpsub driver does not have build time dependencies on the PHY
or DMA drivers. These are runtime hardware restrictions.

Make the two dependencies optional if COMPILE_TEST.

Use drm helpers, drm_format_info_plane_width(),
drm_format_info_plane_height() and drm_format_info_min_pitch() to
calculate sizes for the DMA.

This cleans up the code, but also makes it possible to support more
complex formats (like P030, P230).

The KMS framework uses two slightly different definitions for the state
concept. For a given object (plane, CRTC, encoder, etc., so
drm_$OBJECT_state), the state is the entire state of that object.
However, at the device level, drm_atomic_state refers to a state update
for a limited number of objects.

Thus, drm_atomic_state isn't the entire device state, but only the full
state of some objects in that device. This has been an endless source of
confusion and thus bugs.

We can rename the drm_atomic_state structure to drm_atomic_commit to
make it less confusing.

This patch was created using:

rg -l drm_atomic_state | \
	xargs sed -i 's/drm_atomic_state/drm_atomic_commit/g; s/drm_atomic_commit_helper/drm_atomic_state_helper/g'
mv drivers/gpu/drm/tests/drm_atomic_state_test.c drivers/gpu/drm/tests/drm_atomic_commit_test.c
