V4L/DVB (13236): ir-kbd-i2c: Don't reject unknown I2C addresses 

I do not think it makes sense any longer for ir-kbd-i2c to reject
devices at unknown I2C addresses. The caller can provide all the
details about how the device should be handled. Having to add new
addresses to ir-kbd-i2c so that they aren't rejected is a pain we
don't need. Unsupported devices will be spotted a few lines later
anyway.

This already lets us unlist 2 addresses (0x7a and 0x2d) for which
handling details are always provided by the caller (saa7134-input).
Hopefully we can remove more in the future.
