This series is based on a discussion with Jean on how to get rid of
class-based device probing on muxed segments of a i801-controlled
smbus. i2c_register_spd() could be further optimized for the case that
it's called on a muxed segment, for now go with the minimum of needed
changes.

I don't have such a system with a muxed smbus, therefore the series is
compile-tested only.
