Gaviraju Doddabettahalli Bettegowda d14a7087e2 video: driver: Add changes to calculate auto framerate 
Currently, there is a precision loss while calculating framerate,
this will result in updating framerate multiple times to firmware.
So added change to avoid precision loss in framerate calculation.
