That's the current syntax indeed. Some documentation is found at
lib/librte_eal/common/include/rte_devargs.h:100
Where it is specified that the bus name can be either omitted or
followed by any character, to separate it from the device identifier.
This means that using ':' is fine, as well as '('. As long as the device
PMD afterward ignore the dangling ')' during devargs parsing, this should
be fine.
I don't think this is very clean, but it works.
