msm: mdss: add check to avoid fudge factor for non real time interfaces

Browse source 
Current driver checks if some video interface is connected
in order to apply a fudge factor.
This is expected for real time interfaces, but non real
time interfaces should not account for this extra bandwidth.
This fix adds a check to make sure that for non real time
interfaces the fudge factor does not get applied.
