V4L/DVB (12182): cx18: Add DVB-T support for Yuan MPC-718 cards with an MT352 or ZL10353

Add DVB-T support for Yuan MPC-718 cards with an MT352 or ZL10353 demodulator.

There are apparently some units with a DiBcom demodulator which could be
supported by one of the dib7000 modules - but this is not implemented in the
cx18 driver (yet).

Due to lack of porgramming details for the MT352 and the mt352 module requiring
a "demod_init" function, a "firmware" must be obtained and loaded to get
DVB-T working for Yuan MPC-718 cards with an MT352.
