drm/msm/dpu: split PIPES_PER_STAGE definition per plane and mixer

Browse source

The stage contains configuration for a mixer pair. Currently the plane
supports just one stage and 2 pipes. Quad-pipe support will require
handling 2 stages and 4 pipes at the same time. In preparation for that
add a separate define, PIPES_PER_PLANE, to denote number of pipes that
can be used by the plane.
