Identical configurations of planes can lead to different (and wrong) layer -> pipe routing at HW level, depending on the order of atomic plane changes. For example: - Layer 1 is configured to zpos 0 and thus uses pipe 0. No other layer is enabled. This is a typical situation at boot. - When a compositor takes over and layer 3 is enabled, sun8i_ui_layer_enable() will get called with old_zpos=0 zpos=1, which will lead to incorrect disabling of pipe 0 and enabling of pipe 1. What happens is that sun8i_ui_layer_enable() function may disable blender pipes even if it is no longer assigned to its layer. To correct this, move the routing setup out of individual plane's atomic_update into crtc's atomic_update, where it can be calculated and updated all at once. Remove the atomic_disable callback because it is no longer needed.
