V4L/DVB (13234): IR device at I2C address 0x7a

The i2c core prevents us from probing I2C address 0x7a because it's
not a valid 7-bit address (reserved for 10-bit addressing.) So we must
stop probing this address, and explicitly list all adapters which use
it. Under the assumption that only the Upmost Purple TV adapter uses
this invalid address, this fix should do the trick.
