drm: Allow drivers to indicate the damage helpers to ignore damage clips
commit 35ed38d58257336c1df26b14fd5110b026e2adde 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).
