In Valleyview the DPLL and lane control registers are accessible only
through side band fabric called DPIO. Added two tools to read and write
registers residing in this space.
v2: Moved the core read/write functions to lib/intel_dpio.c based on
Ben's feedback

On SandyBridge, the BLT commands were split from the RENDER commands as
well as the BSD split inherited from Ironlake. So we need to make sure
we do exercise each ring, and in order to do so we also need to make
sure each batch takes longer to execute than it takes for us to
submit it.
v2: Exercise each ring sequentially.

Test that try to exercise the swap paths need to check whether swap is
available, otherwise they'll just oom.

A few of the tools can be performed post-mortem from a different system,
so it is useful to be able to compile those tools on those foreign
systems. Obviously, any program to interact with the PCI device or talk
to GEM will fail on a non-Intel system.
