[PATCH] DVB: Revamp of the TTUSB-DEC driver 

 - Alter hotplug firmware naming to fit in with dvb standard.
 - Use the hotplug firmware loader for 2.6 kernels instead of compiling
   the firmware into the module. 
 - Integrate frontend into ttusb_dec module and remove pseudo-i2c bits,
   move ttusb_dec header into source file.
 - Rudimentary section filter support (enough for scan).

The DEC devices require firmware in order to boot into a mode in
which they are slaves to the PC. See
linux/Documentation/dvb/FIRMWARE for details.
The firmware can be obtained and put into the default
locations as follows:
wget http://hauppauge.lightpath.net/de/dec215a.exe
unzip -j dec215a.exe Software/Oem/STB/App/Boot/STB_PC_T.bin
mv STB_PC_T.bin /usr/lib/hotplug/firmware/dec2000t.bin
