[PATCH] infiniband/mlx5: Remove superfluous include of io-mapping.h

[Chris Wilson]

This file does not use any structs or functions defined by io-mapping.h
(nor does it directly use iomap, ioremap, iounamp or friends). Remove it
to simplify verification of changes to io-mapping.h

Except the commit message, which doesn't follow SubmittingPatches guide,
it looks good.
