Convert the MIPI-DBI-based drivers to shadow-plane helpers. The
drivers vmap/vunmap GEM buffer memory during the atomic commit.
Shadow-plane helpers automate this process.
Patches 1 to 4 prepare the MIPI code for the change and simplify
the rest of the patchset.
Patches 5 to 7 rework the vmap code in the MIPI-DBI drivers and add
shadow-plane helpers. Most of the affected drivers call MIPI-DBI
helpers and get the update automatically. Only ili9225 and st7586
require changes to their source code.
Patch 8 simplifies drm_dev_enter() and _exit(). It's not strictly
needed, but streamlines the driver code and make sense overall.
Testing is welcome, as I don't have any hardware to test these
changes myself.
v2:
* fix vmap()/vaddr confusion (Noralf)
* drop struct mipi_dbi_plane_state (Noralf)
