nfp: add CPP access core Command Push Pull is the name of NFP's network on a chip. PCIe PF can access the interconnect through a number of mappings controlled via Base Access Registers. BARs allow the PF to issue pretty much any command or address any memory on the chip. Add appropriate logic and a handful of helper for simple operations like reading scalars from memories.
