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.
