msm_fb: display: get 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 change is driver change which makes those parameters
target dependent.
