msm: display: provide mdp bandwidth parameters from board file
Underrun issues can be solved by changing mdp bandwidth parameters:
max_bw, ab_factor and ib_factor. However these parameters are not
universally same for all targets, and one set of values that works for
one target could cause underruns or higher power on other
targets. This is board side change.
