nvidia-oot: imx318: fix probe failure

Browse Source 
V4l2 ctrl values are 0 during init time s_ctrl call
from v4l2. Since framerate val parameter is 0, when
set_framerate_ex is called from set_ctrl_ex during
initialization for probing of imx318 sensor, this
results in invalid error and probe failure for imx318.

Assign framerate 'val' to a value from imx318 sensor
device-tree properties within the given range to avoid
probe failure due to this.
