This series refactors blender setup from individual planes to a common
place where it can be performed at once and is easier to reason about.
In the process this fixes a few bugs that allowed blender pipes to be
disabled while corresponding DRM planes were requested to be enabled.
Please take a look. :)
v2:
- use regmap_write where possible
- add review tags
Thank you very much,

2.44.0
From: Ondrej Jirman <[email protected]>
Identical configurations of planes can lead to different (and wrong)
layer -> pipe routing at HW level, depending on the order of atomic
plane changes.
For example:
- Layer 1 is configured to zpos 0 and thus uses pipe 0. No other layer
is enabled. This is a typical situation at boot.
- When a compositor takes over and layer 3 is enabled,
sun8i_ui_layer_enable() will get called with old_zpos=0 zpos=1, which
will lead to incorrect disabling of pipe 0 and enabling of pipe 1.
What happens is that sun8i_ui_layer_enable() function may disable
blender pipes even if it is no longer assigned to its layer.
To correct this, move the routing setup out of individual plane's
atomic_update into crtc's atomic_update, where it can be calculated
and updated all at once.
Remove the atomic_disable callback because it is no longer needed.

From: Ondrej Jirman <[email protected]>
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.
