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).
