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.
