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.

msm: display: change mdp default ib_factor to 150
system profiling found that mdp downscaling needs larger bandwidth
that is related to mdp ab request, so adding scaling factor to mdp ab
calculation reduces the chance of underruns.

ab - scaling factors - port0 and port1 split
ib - 1.5 x ab - no split and same on both ports

This is board file change for ib = 1.5 x ab
commit: fa15f936834ee61cee05a661e6931ecce06afbe1

Unmerged from latest changes. So port it for our board.
