link's check callback is supposed to verify/permit setting it,
however currently nothing restricts it from misusing it
and modifying target object from within.
Make sure that readonly semantics are checked by compiler
to prevent callback's misuse.

xlnx_dp_aux_push_tx_fifo takes an immediate uint8_t and a buffer length,
which must be 1 because that is how many uint8_t's fit in a uint8_t.
Sure enough, that is what xlnx_dp_write passes to it, but the function
is just weird. Therefore, make xlnx_dp_aux_push_tx_fifo look like
xlnx_dp_aux_push_rx_fifo, taking a pointer to the buffer.
