rapidio/tsi721: convert to modular mport driver
This patch adds an option to build device driver for Tsi721 PCIe-to-SRIO bridge device as a kernel module. Currently this module cannot be unloaded because the existing RapidIO subsystem code does not support dynamic removal of local RapidIO controllers (TODO).
