Hello build bot (Jenkins),

ft2232_spi: Add FTDI search by description.

This adds to the search-by-serial functionality with
search-by-description (product string). This is useful when e.g. one has
multiple FTDIs in a system and wants the serial numbers to reflect the
system-level serial number, and the description to reflect the
subcomponent names.

Tested manually by running with both serial and description searches, on
a machine with multiple FTDIs plugged in. Ensured that when two devices
with the same vid/pid/serial number are plugged in, description can still
be used to differentiate.

Original version of this code used the original single "arg" char*, but
on further thought, this wasn't worth the readability and functionality
losses. The new version with arg2 gets rid of several lines of code, the
gotos, and adds the ability to filter by both description and serial
simultaneously.
