USB: serial: Updated support for ICOM devices

I found the original patch on the db0fhn repeater wiki (couldn't find the email
of the origial author) I guess it was never commited.
I updated and added some Icom HAM-radio devices to the ftdi driver.
Added extra comments to make clear what devices it are.
