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.
