nfp: introduce dev_info static chip data
In preparation for supporting new chip add a driver data structure
which will hold per-chip-version information such as register
offsets.
Plumb it through to the relevant functions (nfpcore and nfp_net).
For now only a very simple member holding chip names is added,
following commits will add more.
