media: atomisp: gc0310: Limit max exposure value to mode-height + vblank

When an exposure value > (mode-height + vblank) gets set the sensor will
automatically increase vblank, lowering the framerate.

This is not desirable, limit exposure the maximum exposure to mode-height +
vblank to avoid the unwanted framerate slowdown.
