We don't emulate slave mode so related registers are not needed.
[lh]sadr are only retained to avoid too many warnings and simplify
debugging but sdata is not even correct because device has a 4 byte
FIFO instead so just remove this unimplemented register for now.
The intr register is also not implemented correctly, it is for
diagnostics and normally not even visible on device without explicitly
enabling it. As no guests are known to need this remove it as well.
