[PATCH] openrisc: remove the redundant of_platform_populate

[Rob Herring]

The of_platform_populate call in the openrisc arch code is now redundant
as the DT core provides a default call. Openrisc has a NULL match table
which means only top level nodes with compatible strings will have
devices creates. The default version will also descend nodes in the
match table such as "simple-bus" which should be fine as openrisc
doesn't have any of these (though it is preferred that memory-mapped
peripherals be grouped under a bus node(s)).

This looks fine to me.  I am not sure if you got a reply from Jonas, but 
he hasn't been active maintainer for a while.

We are working on getting this sorted out.
