In some cases the interrupt line of a device is optional. Introduce a new platform_get_irq_optional() that works much like platform_get_irq() but does not output an error on failure to find the interrupt.

PowerPC platforms don't use the generic of/platform code to populate the devices from DT. Therefore the generic device linking code is never used in PowerPC. Compile it out to avoid warning about unused functions. If a specific PowerPC platform wants to use this code in the future, bringing this back for PowerPC would be trivial. We'll just need to export of_link_to_suppliers() and then let the machine specific files do the linking as they populate the devices from DT.
