media: video: tegra: ar0832: adjust frame rate
Change line_length for 1080p mode in order to change
frame rate from 31.30 to 29.50 fps.
The reason that new fps is not 30 is because flicker
detection requires fps not to be multiples of 60/50Hz.
This change helps save power and lower the chance of frame
drop.
