rapidio/tsi721: add option to configure direct mapping of IB window
Add an option to configure mapping of Inbound Window without RIO-to-PCIe address translation. If a local memory buffer is not properly aligned to meet HW requirements for RapidIO address mapping with address translation, caller can request an inbound window with matching RapidIO address assigned to it. This implementation selects RapidIO base address and size for inbound window that are capable to accommodate the local memory buffer.
