USB: ark3116: add IrDA support for Gembird UIR-22
Add IrDA support to ark3116 driver. This makes Gembird UIR-22 USB to IrDA
adapter work (vendor ID 0x18ec, device ID 0x3118). This adapter contains
ARK3116T USB serial chip and an IrDA transceiver, thus a command like
"irattach /dev/ttyUSB0 -s" is needed.
All magic numbers were captured using usbsnoop from windows driver that
came with the device.
