f3286a3af8 tile: support multiple mPIPE shims in tilegx network driver 
The initial driver support was for a single mPIPE shim on the chip
(as is the case for the Gx36 hardware).  The Gx72 chip has two mPIPE
shims, so we extend the driver to handle that case.

4875f69fec arch/tile: provide kernel support for the tilegx mPIPE shim 
The TILE-Gx chip includes a packet-processing network engine called
mPIPE ("Multicore Programmable Intelligent Packet Engine").  This
change adds support for using the mPIPE engine from within the
kernel.  The engine has more functionality than is exposed here,
but to keep the kernel code and binary simpler, this is a subset
of the full API designed to enable standard Linux networking only.
