media: rcar-vin: Fix image alignment for setting pre clipping 

In Video Pixel/Line Pre-Clip Register, the setting value can be
set in 1 line unit, but it can only be specified as a multiple of
4 by v4l_bound_align_image function().
So correct that it can be specified in 1 line unit with this patch.
