disp: msm: sde: proper allocation of dcwb for LMs

Browse Source 
During dcwb mixer allocation, resource manager allocates
the first available mixer in the free list. In dual display
uses case with 1 1 1 topology if only secondary is running
CWB then, resource manager allocates DCWB0 which leads to wb
timeout due to HW does not have the connection between LM1
and DCWB0. This change allocates proper dcwb for the LMs in RM.
