[PATCH rdma-next V2 5/9] IB/ocrdma: Move user vendor structures

[Leon Romanovsky <leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

This patch moves ocrdma vendor's specific structures to
common UAPI folder which will be visible to all consumers.

These structures are used by user-space library driver
(libmlx4) and currently manually copied to that library.

This move will allow cross-compile against these files and
simplify introduction of vendor specific data.

In addition, it changes types to be __uXX instead of uXX.
