This patch adds support for the UB435-Q V2. You might need to
use the device once with the Windows driver provided by KWorld
in order to permanently reprogram the device descriptors. Thanks
to Jarod Wilson for the initial attempt at adding support for this
device.

Downloading new firmware for DRX-K demodulator is not obligatory but
usually it offers important bug fixes compared to default firmware
burned into chip rom. DRX-K demod driver will continue even without
the firmware, but in that case it will print warning to system log
to tip user he should install firmware.

Newer em28xx devices have 2 buses. Change the logic to allow
using both buses.
This patch was generated by this small script:
for i in drivers/media/usb/em28xx/*.c; do
sed 's,->i2c_adap,->i2c_adap[dev->def_i2c_bus],g;s,->i2c_client,->i2c_client[dev->def_i2c_bus],'
done
Of course, em28xx.h needed manual edit.

Putting em28xx in suspend mode when a feed stops is just plain
wrong. Every time a new PES filter is changed, the DVB demux
code will stop the current feed, and then start a new one.
If are there any code that switches off the frontend, via
some GPIO setting, this would make the DVB fail.
This condition was actually trigged with one device, during
DVB scan, as, during scan, it is common that userspace apps
to change the filter several times, in order to get all
tables.
Also, this is not needed at all, since the em28xx code already
hooks into ops.ts_bus_ctrl(). This warrants that em28xx can
check there if DVB frontend is in usage or not. The code there
already puts the device on suspend mode, if the DVB frontend
is not used (closed).

The current enpoint logic ignores all bulk endpoints and uses
a fixed mapping between endpint addresses and the supported
data stream types (analog/audio/DVB):
Ep 0x82, isoc => analog
Ep 0x83, isoc => audio
Ep 0x84, isoc => DVB
Now that the code can also do bulk transfers, the endpoint
logic has to be extended to also consider bulk endpoints.
The new logic preserves backwards compatibility and reflects
the endpoint configurations we have seen so far:
Ep 0x82, isoc => analog
Ep 0x82, bulk => analog
Ep 0x83, isoc* => audio
Ep 0x84, isoc => digital
Ep 0x84, bulk => analog or digital**
(*: audio should always be isoc)
(**: analog, if ep 0x82 is isoc, otherwise digital)
