Add support for the Amontec JTAGkey2

Add support for the Amontec JTAGkey2, see
http://www.amontec.com/jtagkey2.shtml
http://www.amontec.com/jtagkey.shtml.

This FTDI 2232H variant has an additional output enable, which will be
set to its "on" (L) when CS is pulled low. But it lacks a power supply
and you need an external 3.3V source.

The attached patch adds "jtagkey" as "type" parameter for ft2232_spi. It
should work with all JTAGkeys (JTAGkey, JTAGkey-tiny and JTAGkey2) but I
only have a JTAGkey2 here for testing.

Add all FT2232H/FT4232H based programmers to the list printed with
flashrom -L

Corresponding to flashrom svn r1119.
