2018-03-22npu2: Remove DD1 supportAndrew Donnellan1-21/+3
Major changes in the NPU between DD1 and DD2 necessitated a fair bit of revision-specific code. Now that all our lab machines are DD2, we no longer test anything on DD1 and it's time to get rid of it. Remove DD1-specific code and abort probe if we're running on a DD1 machine.

2018-03-01npu2: Split out common helper functions into separate fileAndrew Donnellan1-0/+114
Split out common helper functions for NPU register access into a separate file, as these will be used extensively by both NVLink and OpenCAPI code.
