saa7134: fix warm Medion 7134 EEPROM read

commit 5a91206ff0d0548939f3e85a65fb76b400fb0e89 upstream.

When saa7134 module driving a Medion 7134 card is reloaded reads of this
card EEPROM (required for automatic detection of tuner model) will be
corrupted due to I2C gate in DVB-T demod being left closed.
This sometimes also happens on first saa7134 module load after a warm
reboot.

Fix this by opening this I2C gate before doing EEPROM read during i2c
initialization.
