Modify AFU configurations for new BBS(Blue Bitstream) of A10 on N3000 card:
- AFU register access: RTL changes the UPL(User Programable 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.
Fixes: c01c748e4ae6 ("net/ipn3ke: add new driver")
