[PATCH] ASoC: pcm512x: use DIV_ROUND_CLOSEST_ULL() from kernel.h

[Javi Merino]

Now that the kernel provides DIV_ROUND_CLOSEST_ULL(), drop the internal
implementation and use the kernel one.

Patches in the -mm tree now provide a DIV_ROUND_CLOSEST_ULL()
implementation in kernel.h[0].  If I understand it correctly, this
patch should go via the -mm tree as well with appropriate Acks from
the maintainers.
