I would have expected this to be 0x2000 as that's what the older
platforms have been using for the dp serdes table so far. Without access
to any documentation it's hard to tell whether everyone's just been
cargo-culting all along or if there's actually something there at offset
0x2000.

Vinod, could you shed some light on this as presumably you have access
to some documentation?
