Refactor the existing simple-display callbacks such that they invoke
helpers compatible with regular atomic modesetting. Allows for adding
mipi-dbi drives that do not require simple-display helpers.
Provide initializer macro for elements of the regular modesetting
pipeline. These will be used by drivers to integrate mipi-dbi helpers.
Also provide initializer macros for the plane formats.
As the new helpers are DRM functions, add the drm_ prefix. Mipi-dbi
interfaces currently lack this.
v3:
- fix uninitialized variable (David)
- document public interfaces (David)
- mention format macros in commit message (David)
