V4L: saa7134: Copy tuner data earlier to avoid overwriting manual tuner type

(cherry picked from commit d53687d1)

Copy tuner data earlier in init to avoid overwriting manual tuner type

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.
