Herton Ronaldo Krzesinski 0a062033f7 Revert "V4L/DVB (11906): saa7134: Use v4l bounding/alignment function"
This reverts commit bc52d6eb44.

On newer kernels, a saa7134 board stopped to display TV video output
properly. After a bisect, I found it as the commit causing the issue.
Turns out that v4l_bound_align_image isn't doing the same bounding
calculation as manually done previously in saa7134_try_fmt_vid_cap.

What isn't equal is the calculation done in clamp align, while
previously it did "f->fmt.pix.width &= ~0x03", clamp_align function
does "Round to nearest aligned value" as stated in the comment, which
yields a different result. If I comment the round calculation in
clamp_align like this: "x = (x /*+ (1 << (align - 1))*/) & mask",
I get it fixed too, because this way the calculation is the same then.
