Javier Martinez Canillas 45aafb5075 drm: Allow drivers to indicate the damage helpers to ignore damage clips ...

commit 35ed38d582 upstream.

It allows drivers to set a struct drm_plane_state .ignore_damage_clips in
their plane's .atomic_check callback, as an indication to damage helpers
such as drm_atomic_helper_damage_iter_init() that the damage clips should
be ignored.

To be used by drivers that do per-buffer (e.g: virtio-gpu) uploads (rather
than per-plane uploads), since these type of drivers need to handle buffer
damages instead of frame damages.

That way, these drivers could force a full plane update if the framebuffer
attached to a plane's state has changed since the last update (page-flip).

Fixes: 01f05940a9 ("drm/virtio: Enable fb damage clips property for the primary plane")
