It's deprecated for platform_devices, but should still be used for
other bus types that don't provide the device driver with a list of
irqs. For platform devices it is best to use the platform_bus irq
table since that is portable regardless of how the device is
instantiated.

As for not exporting of_irq_count(), I don't have a problem with it,
but only if there is a user. It sounds like with the rework you
discussed with Jean-Christophe that it is no longer the case.
