Horizontal and vertical scaling range are according to the following equations.
If (SRC_Width >= 64 x DST_Width) { Exit(-1); /* Out of Horizontal scale range}
If (SRC_Height >= 64 x DST_Height) { Exit(-1); /* Out of Vertical scale range}
fimc_check_scaler_ratio() is used to check if horizontal and vertical
scale range are valid or not. To use fimc_check_scaler_ratio,
source and destination format should be set by VIDIOC_S_FMT.
And in case of scaling up, it doesn't have to check the scale range.
