This is based on an earlier patch from Rob Herring

[off-list ref]

Add OF match table to enable OF style driver binding. The dts entry

is like

this:

pmu {
   compatible = "arm,cortex-a9-pmu";
   interrupts = <100 101>;
};

The use of pdev->id as an index breaks with OF device binding, so

set the type

based on the OF compatible string.

This modification sets the PMU hardware type based on data embedded

in the

binding, allowing easy addition of new PMU types in future.

Support for new PMU types not provided by devicetree can be added

later using

quoted

platform_device_id tables in a similar fashion.

 Rob: would you be happy to merge this into your tree? or would you
 rather I sent it through Russell?
