USB: ftdi_sio: Support for more JTAG adaptors

[PATCH] ftdi_sio: add support for more FTDI based JTAG adaptors

There are more devices similar to the Olimex JTAG adaptor, in that the first
port of the FT2232C is used for JTAG, and only the second port is available as
UART.

I have thus renamed ftdi_olimex_{probe,quirk} to ftdi_jtag_{probe,quirk} and
added vendor/product ID's for the OpenMoko Neo1973 Debug Board as well as the
OOCDlink device.

I've also updated the KERN_INFO message sent to userspace to remove the word
'olimex' and an extra '\n' that was causing an empty line in dmesg.
