I think in general, this is the right direction; but I'm not convinced
that the right pattern or form has been found yet.  What I don't like
on this particular patch is that it still hooks of-specific stuff into
an arbitrary point in the probe routine.

I'd like to see some pattern for retrieving or populating a
platform_data structure when one isn't already provided, and
regardless of the data source.

So, I guess I'm saying that I agree with the approach, but I think a
better pattern would be to factor out all of the platform_data
fetching code into a separate function and keep probe() focused on
initializing the device based on a pdata structure returned by it.  It
will take a bit of experimentation to come up with the best form for
the pdata fetching function, but it will be better contained if it is
all at a single place.
