I have finally dug into the usbftdi driver code and found that
it has hard coded limitations to specific devices.
I just had to add the one I needed (usb403,6015) to the
hard coded list and recompile.

Below is the significant diff.

Compiling this relies on a file sys/usb/usbdevs.h defining
the vendor/product ids, which is apparently built from some
source file whose OpenIndiana variant I could not find.
I used one from FreeBSD, but it does not contain the one
for MARVELL_SHEEVAPLUG_JTAG.
