Chris Pascoe 702a67624e V4L/DVB (6655): Add support for MT352-based DViCO FusionHDTV DVB-T NANO devices 
There are at least three variants of the DViCO FusionHDTV DVB-T NANO that
share the same USB device ID.  The first (ZL10353 w/ firmware in ROM) is
already supported; the latter two both require firmware and have either
an MT352 or ZL10353 demodulator, and have a different IR receiver from the
first.

This introduces a new identify_state that can tell the difference between a
"warm" device which is running the embedded firmware, and a "cold" device
that needs us to upload firmware to it before it will work.  We patch the
uploaded device ID (like we do for other bluebird devices) to make it easy
to identify the particular device variant when it reattaches.

NB: These devices use a different firmware file from previous bluebird
    devices.  You need a new firmware file to make this work.

/* DVB USB compliant linux driver for Conexant USB reference design.
*
* The Conexant reference design I saw on their website was only for analogue
* capturing (using the cx25842). The box I took to write this driver (reverse
* engineered) is the one labeled Medion MD95700. In addition to the cx25842
* for analogue capturing it also has a cx22702 DVB-T demodulator on the main
* board. Besides it has a atiremote (X10) and a USB2.0 hub onboard.
*
* Maybe it is a little bit premature to call this driver cxusb, but I assume
* the USB protocol is identical or at least inherited from the reference
* design, so it can be reused for the "analogue-only" device (if it will
* appear at all).
*
* TODO: Use the cx25840-driver for the analogue part
