MIF frequency optimization for 60fps video recording use-case

Browse source 
This CL sets the MIF min clock frequency to 1539MHz, which based on
initial ODPM and MIPS measurements shows benefit both in terms of power
consumption and cycles-per-instructions (CPI), reducing the gap with R4
device.

L10 power and performance impact tests will update on the bug.
