From Michael Hennerich <michael.hennerich@analog.com>
   * src/tap/parport/ftdi.c (ftdi_generic_open): Detect
     BFIN-UJTAG cable.
   * src/tap/cable.c (ft2232_bfin_ujtag_cable_driver): Declare.
     (cable_drivers): Add ft2232_bfin_ujtag_cable_driver.
   * src/tap/cable/ft2232.c (BIT_BFIN_UJTAG_nTRST,
     BIT_BFIN_UJTAG_nLED, BITMASK_BFIN_UJTAG_nTRST,
     BITMASK_BFIN_UJTAG_nLED): Define.
     (ft2232_bfin_ujtag_init): New.
     (ft2232_bfin_ujtag_done): New.
     (ft2232_bfin_ujtag_cable_driver): Define.
