rapidio: add udev notification
Add RapidIO-specific modalias generation to enable udev notifications about RapidIO-specific events. The RapidIO modalias string format is shown below: "rapidio:vNNNNdNNNNavNNNNadNNNN" Where: v - Device Vendor ID (16 bit), d - Device ID (16 bit), av - Assembly Vendor ID (16 bit), ad - Assembly ID (16 bit), as they are reported in corresponding Capability Registers (CARs) of each RapidIO device.
