msm_fb: display: keep a minimum mdp ib bandwidth request

The calculated ab and ib bandwidth requests are very small which cause
underruns if mdp composites only very small layers. For these use
cases keeping a minimum ib request based on the baselayer size can
prevent underruns and no power impact is observed.
