net/ipn3ke: modify AFU configurations

Modify AFU configurations for new BBS (Blue Bitstream) of A10 on N3000
card:
- AFU register access: RTL changes the UPL (User Programmable Logic
which is the container of vBNG IP) base address and the read/write
commands of register indirect access.
- Poll the INIT_STS register to wait for the vBNG IP and DDR reset
completion.
- Refine log for debug: print UPL_version not only for vBNG bit stream,
but also for other bit streams.
