[Pdbg] [PATCH v2] main: Set I2C backend device specified in arguments

[Alistair Popple]

Thanks Artem for the contibution and fix! I've just pushed it to master. For 
background the orignal idea was to pass these sorts of parameters via device-
tree, but I can see why being able to set it on the command line would be 
helpful.
