V4L/DVB (5321): Saa7134-dvb: initialize the dvb frontend in dvb_init
The hardware is completely initialized afterwards, especially the
tda10046 has its firmware - which is also necessary in analog mode
of some hybrid boards.
Calling the sleep function afterwards saves power and definitely puts
hybrid boards into analog mode without additional code elsewere.
