media: mt9m114: Tweak default hblank and vblank for more accurate fps
The PLL gets programmed to achieve a 48 MHz pixelclock, with the current
vblank + hblank defaults this results in a fps of:
48000000 / ((1296 + 307) * (976 + 23) = 29.974 fps
Tweak the defaults to get closer to 30 fps:
48000000 / ((1296 + 308) * (976 + 21) = 30.015 fps
This improves things from being 0.026 fps too low to 0.015 fps too high.
