  swscale: Update bitdepth range check

This commit is a noop.

Up to 14 bits is supported since fa36f334. This commits pushes the
limit to 15 bits but we don't seem to have pixel formats that enters in
that category.

12:03 <ubitux> so what's your opinion? should we move to 15 even if unused currently to make it consistent with libav and the function names, or keep our 14 suggesting there might be an issue with 15?
12:05 <ubitux> (functions are called hScale8To15_c, hScale16To15_c, ff_hscale8to15, ...)
12:06 <michaelni> I prefer to keep 14 until theres a case that allows us to test this and i suspect it will not work with 15 at least not all the code
