Support for newer revisions of the MyGica T230C, shipping with a
different USB pid. Although sometimes referred to as T230C2, the device
is sold under its original name T230C.

Besides a slightly different PCB layout and some different minor
components, it utilizes the same bridge, demodulator and tuner as the
older revision. However, it requires a fixed TS clock frequency of 10
MHz to tune to some muxes.

Tested with various DVB-T2 HEVC and DVB-C channels.
