[PATCH RFC v1 3/4] ntb: prepare to build the 'data transport' as a separate module

[Gerhard Sittig <gsi@denx.de>]

Export those routines of the data transport which the PCI NTB hardware
drivers will reference, and provide module properties such that the data
transport over PCI NTB can build as a separate module.

This change does not alter the Makefile, the data transport still gets
statically linked against the driver for Intel hardware support.
