msm: mdss: fix frame rate calculation for DP interface

Browse source 
In the current implementation the frame rate value for
DP interface is returning wrong value which in turn
results in wrong estimate of bandwidth votes and causes
underrun on DP panels. Fix the issue by back calculating
frame rate from pixel clock value read from EDID.
