[dpdk-dev] [DPDK v2] net/ipn3ke: modifications on AFU configurations

[Dan Wei]

Modify AFU configurations for new Blue Bitstream of A10 on N3000 card:
- AFU register access: RTL changes the UPL base address and the read/write
commands of register indirect access.
- Add delays to wait for the HW reset completion.
- Refine log for debug: print UPL_version not only for vBNG bit stream,
but also for other bit streams
