drm/plane-helper: Add drm_plane_helper_check_state()
Add a version of drm_plane_helper_check_update() which takes a plane
state instead of having the caller pass in everything.
And to reduce code duplication, let's reimplement
drm_plane_helper_check_update() in terms of the new function, by
having a tempororary plane state on the stack.
v2: Add a note that the functions modifies the state (Chris)
v3: Fix drm_plane_helper_check_update() y coordinates (Daniel Kurtz)
