Noralf Trønnes af74138160 drm/tinydrm: Use damage helper for dirtyfb
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
