Xc2028.3028 has two type of firmwares: audio-standard specific ones and
baseband MTS firmwares. MTS firmwares provide stereo decoding for 6 MHz
BTSC/EIAJ and for monoaural audio decoding on 8 MHz firmwares.
It seems that the option to use MTS or a standard-specific audio decoding
depends on the way xc2028/3028 is connected.
Instead of wasting 32 (or 64 bits) to signalize if the driver needs to use MTS
firmware, this patch converts it to a bitfield that can be shared with other
proprieties of xc2028/3028.

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.

Add support for DViCO's Dual Digital 4 with xc3028 tuner, zl10353 DVB-T
demodulator and a new-style I2C IR remote control receiver.
This would not have been possible without the work of and advice from
Mike Krufky, who originally got the Dual Digital 4 and second-gen DVB-T
NANO devices working with the out-of-tree XC3028 driver.
I converted it to use the in-tree XC3028 driver (after making it suitable
for our use), and added the IR remote control support based on his advice.
NB: a firmware package is required to use this device.
