As mentioned in v1, I think we should not have it in the generic i2c
headers yet. a) it makes backporting more difficult and b) we need to
find the optimal generic set of parameters which is a seperate issue.

Minor nit: I think there is no need for the extra blank line, but I'll
let you decide.

'pca_i2c_bus_settings' or similar?

Rest looks good!
