This switches to drm_atomic_helper_dirtyfb() as the framebuffer dirty

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.
v2: Remove fb check in mipi_dbi_enable_flush() it can't be NULL

Tested with ST7586 on LEGO MINDSTORMS EV3 and ILI9225 on
BeagleBone Green. (FWIW, I encounter other issues that had to
be fixed to make things work on both of these, but none were
actually related to this series.)
Actually, I have to take this back. It appears that the problems
that I had on LEGO MINDSTORMS EV3 are actually caused by this
series. I did a git bisect to be sure and ended up with this
patch as the bad commit. I'm guessing that the damage helper
must be causing some kind of memory corruption. Here is the
crash I am getting:
Unable to handle kernel NULL pointer dereference at virtual address 00000004
