[linux-dvb] Frontend patch

[Ragnar Sundblad <ragge@nada.kth.se>]

This is a fix for alps_tdlb7.c to drive the tuner PLL power
according to the specification from ALPS. I need it to have
the tuner work reliably, for at least one other person
(or rather, card :-) it doesn't seem to harm.
I have only tried it with DVB, but it should be applicable
to dvb-kernel too.

I believe this should be applied to the cvs code.
