V4L/DVB (7654): tda10086: make the xtal frequency a configuration option
Some DVB-S boards, i.e. with the SD1878 tuner, use a 4 MHz reference frequency.
This reqires a different setup of the clock PLL.
This patch adds an enum to the tda10086_config struct and sets the proper
values for the boards.
This patch also fixes the DVB-S section of the MD7134_BRIDGE_2
