V4L/DVB (7392): saa7134: support 2nd DVB-S section of the MD8800
There are some restrictions: - The 2nd DVB-S section will only work if the 1st is configured for DVB-S too. so "options saa7134-dvb use_frontend=0,1" won't work. - Currently it is not possible to set the higher LNB supply voltages, so 14V instead of 13V in the 2nd section. - It is not possibe to turn off the 2nd LNB supply independently. This comes from the problem that the 2nd section can't access the i2c interface of the LNB supply chip.
