drm/komeda: Add rotation support on Komeda driver

Browse source

- Adds rotation property to plane.
- Komeda display rotation support diverges from the specific formats,
so need to check the user required rotation type with the format caps
and reject the commit if it can not be supported.
- In the layer validate flow, sets the rotation value to the layer
state. If r90 or r270, swap the width and height of the data flow
for next stage.
