54c33a4fcf drm/sun4i: Nuke mixer pointer from layer code 
It's not used anymore, so remove it. This allows trully independent
layer state from mixer.

bb1d2ddee5 drm/sun4i: layer: replace mixer with layer struct 
This allows to almost completely decouple layer code from mixer. This is
important for DE33.

515441734c drm/sun4i: layers: add physical index arg 
This avoids plane mapping in layers code, which allows future
refactoring, when layer code will move away from accessing mixer
structure.

37aba59f5f drm/sun4i: layers: Make regmap for layers configurable 
Till DE33, there were no reason to decouple registers from mixer.
However, with future new plane driver, this will be necessary.

4fa45b04a4 drm/sun4i: layer: move num of planes calc out of layer code 
With DE33, number of planes no longer depends on mixer because layers
are shared between all mixers.

Get this value via parameter, so DE specific code can fill in proper
value.

feea4205ef drm/sun4i: de2/de3: Move plane type determination to mixer 
Plane type determination logic inside layer init functions doesn't allow
index register to be repurposed to plane sequence, which it almost is.

So move out the logic to mixer, which allows further rework for DE33
support.

134155a50c drm/sun4i: Unify sun8i_*_layer structs 
These structs are identical, use a single struct to represent private
data for the DRM plane. This is a preparation for configuring layer
routing from the CRTC (mixer) instead of current approach of setting
up routing from individual layer's atomic_update callback.

4b09c07383 drm/sun4i: Rework DE2 register defines 
Most, if not all, registers found in DE2 still exists in DE3. However,
units are on different base addresses.

To prepare for addition of DE3 support, registers macros are reworked so
they take base address as parameter.

5bb5f5dafa drm/sun4i: Reorganize UI layer code in DE2 
Till now, DE2 driver supported only UI planes. Before we add support for
VI planes, lets split out UI layer specific code from common parts. This
commit does the following:
- renames sun8i_layer.c to sun8i_ui_layer.c
- moves UI channel specific code to sun8i_ui_layer.c
- moves common code from sun8i_layer.c to sun8i_mixer.c
- renames function and structure names so it is apparent where they
belong to

No functional change is made.
