Increase MIF frequency for 30fps

This CL increases min MIF frequency to 1352000 in 30fps mode.
Although the MIF power consumption increases due to this
change, but the reduction in CPU cycles results in over-all SoC
power saving. This change also doesn't negatively impact framedrop
rate.

P22 change is ag/19820773.
