drm/vc4: Drop planes that are completely off-screen or 0 crtc size
It is permitted for a plane to be configured such that none
of it is on-screen via either negative dest rectangle X,Y
offset, or an offset that is greater than the crtc dimensions.
These planes were resized via drm_atomic_helper_check_plane_state
such that the source rectangle had a zero width or height, but
they still created a dlist entry even though they contributed
no pixels. In the case of vc6_plane_mode_set, that it could result
in negative values being written into registers, which caused
incorrect behaviour.
Drop planes that result in a source width or height of 0 pixels
or an on-screen size of 0 pixels to avoid the incorrect rendering.
