drm/tinydrm: Make fb_dirty into a lower level hook
mipi_dbi_enable_flush() wants to call the fb->dirty() hook from the
bowels of the .atomic_enable() hook. That prevents us from taking the
plane mutex in fb->dirty() unless we also plumb down the acquire
context.
Instead it seems simpler to split the fb->dirty() into a tinydrm
specific lower level hook that can be called from
mipi_dbi_enable_flush() and from a generic higher level
tinydrm_fb_dirty() helper. As we don't have a tinydrm specific
vfuncs table we'll just stick it into tinydrm_device directly
for now.
v2: Deal with the fb->dirty() in tinydrm_display_pipe_update() as well (Noralf)
