Subject: [RFC/PATCH] drivers/of/platform: Add powerpc 4xx embedded busses to
 default list

This allow to (slowly) migrate those embedded platforms
to of_platform_default_populate()

I'm here to collect acks (or comments :-) I'd like this to go via
the powerpc tree along with the patches converting some of the
platforms. I'll be adding more bus types if/when I start tackling
other powerpc embedded families but for now I'm dealing with 4xx.
