arch/tile: provide kernel support for the tilegx TRIO shim
Provide kernel support for the tilegx "Transaction I/O" (TRIO) on-chip hardware. This hardware implements the PCIe interface for tilegx; the driver changes to use TRIO for PCIe are in a subsequent commit. The change is layered on top of the tilegx GXIO IORPC subsystem. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
