I believe Andy was suggesting a function 'similar to' that one rather
than actually using platform_get_irq.

It's not an area I know all that much about either, but there
are moves to try and move the boiler plat needed to get the same
parameters from devicetree and acpi into core library code so
that a single function can be called to get the parameter in
either case.
