rapidio: add outbound window support
Add RapidIO controller (mport) outbound window configuration operations.
This patch is a part of the original patch submitted by Li Yang:
https://lists.ozlabs.org/pipermail/linuxppc-dev/2009-April/071210.html
For some reason the original part was not applied to mainline code
tree. The inbound window mapping part has been applied later during
tsi721 mport driver submission. Now goes the second part with
corresponding HW support.
