The i2c probe functions here don't use the id information provided in
their second argument, so the single-parameter i2c probe function
("probe_new") can be used instead.
This avoids scanning the identifier tables during probes.

This is useful, helps deprecating the old probe method:

Applied to powerpc/next.
