V4L/DVB (10632): Added support for AVerMedia Cardbus Hybrid remote control

Added support for I2C device at address 0x40 and subaddress 0x0d/0x0b
that provides remote control key reading support for AVerMedia Cardbus
Hybrid card, possibly for other AVerMedia Cardbus cards.

The I2C address 0x40 doesn't like the SAA7134's 0xfd quirk, so it was
disabled.
