From: Liviu Dudau <Liviu.Dudau@xxxxxxx>
Currently the tda998x driver only attempts to instantiate the CEC at I2C
address 0x34, meaning that if the CEC is instead at 0x35 (for example,
due to a conflict with another device) we will not be able to use it.
Attempt to handle some such situations by trying to instantiate the CEC
at 0x35 if we fail at 0x34.

I'm aware this isn't wonderful and is tied in with the general questions
about how to enumerate decomposed video devices, I'm partly looking for
feedback on the best way forwards here.
