[PATCH] saa7134: Copy tuner data earlier in init to avoid overwriting manual tuner type

[Simon Arlott <simon@fire.lp0.eu>]

When saa7134_board_init2 runs, it immediately overwrites the current value
(set earlier from module parameter) of tuner_type with the static values,
and then does autodetection. This patch moves the tuner_addr copy to earlier
in saa7134_initdev and removes the tuner_type copy from saa7134_board_init2.

Autodetection could still potentially change to the wrong tuner type, but it
is now possible to override the default type for the card again.

My card's tuner is configured with autodetection from eeprom, so I don't 
need to manually set the tuner. I've checked that the autodetection still 
works for my card.
