disp: msm: sde: refactor use of master_plane_id

Selaa lähdekoodia 
During plane setup, when a master plane ID is provided it means we
are initializing a slave plane for HW shared by the given master ID.
When master plane ID is 0 it means this is the master. This change
refactors the code to make this clear.
