drm/tinydrm: Fix fbdev pixel format
...
Due to copy/paste error, the fbdev format was changed to 32bpp = XRGB8888
which is an emulated format for the RGB565 drivers. Revert to to using the
fallback which is dev->mode_config.preferred_depth for the drivers that
set it or 32bpp for those that don't (repaper, st7586).

drm/tinydrm: Use drm_dev_enter/exit()
...
This protects device resources from use after device removal.
There are 3 ways for driver-device unbinding to happen:
- The driver module is unloaded causing the driver to be unregistered.
This can't happen as long as there are open file handles because a
reference is taken on the module.
- The device is removed (Device Tree overlay unloading).
This can happen at any time.
- The driver sysfs unbind file can be used to unbind the driver from the
device. This can happen any time.
v2: Since drm_atomic_helper_shutdown() has to be called after
drm_dev_unplug() we don't want do block ->disable after unplug.

This switches to drm_atomic_helper_dirtyfb() as the framebuffer dirty
handler. All flushing will now happen in the pipe functions.
Also enable the damage plane property for all except repaper which can
only do full updates.
ili9225:
This change made ili9225_init() equal to mipi_dbi_init() so use it.
v3: Include vblank header (Sam)
ili9225 and st7586 can't use mipi_dbi_enable_flush() (David)
v2: Remove fb check in mipi_dbi_enable_flush() it can't be NULL

drm/tinydrm: do not reply on drmP.h from drm_gem_cma_helper.h
...
drmP.h was the only header file in the past and a lot
of files rely on that drmP.h defines everything.
The goal is to one day to delete drmP.h and
as a step towards this it will no longer be included in the
headers files in include/drm/
To prepare tinydrm/ for this add dependencies that
othwewise was pulled in by drmP.h from drm_gem_cma_helper.h
To avoid that tinydrm.h became "include everything",
push include files to the individual drivers.
