transceiver: usrp1: select single dboard use at compile time

The following option selects single daughterboard use on
side A only. Otherwise, the default setting is TX on A and
Rx on B.

  ./configure --with-singledb

Other options are possible, as per the following enum, but
for simplicity with configure options, there are only two
choices.

  enum dboardConfigType {
    TXA_RXB,
    TXB_RXA,
    TXA_RXA,
    TXB_RXB
  };
