We make small modifications to the rng files to allow the relaxng-to-proto
script to infer XML attribute types better.

1. Make iobase and irq refs so we can override their types in the script.
2. Replace deviceName with absFilePath so that vdpa devices get fuzzed correctly
with file paths.
3. The relaxng-to-proto script does not handle regexes, so convert some of them
to <choice> containing <value>.
