V4L/DVB (13493): TeVii S470 and TBS 6920 fixes
The new hardware design applied for this cards.
Silicon Labs C8051F300 microcontroller is used for LNB power control.
It connected to cx23885 GPIO pins:
GPIO0 - P0.3 data
GPIO1 - P0.2 reset
GPIO2 - P0.1 clk
GPIO3 - P0.0 busy
Tevii S470 based on Montage Technology M88TS2020 digital satellite tuner
and M88DS3000 advanced DVB-S/S2 demodulator.
