When userspace needs to find a specific device, it currently isn't easy to resolve a /sys/devices/ path from a specific device tree node. Nor is it easy to obtain the compatible list for devices. This patch generalizes the code that inserts OF_* values into the uevent device attribute so that any device that is attached to an OF node will have that information exported to userspace. Without this patch only platform devices and some powerpc-specific busses have access to this data. The original function also creates a MODALIAS property for the compatible list, but that code has not been generalized into the common case because it has the potential to break module loading on a lot of bus types. Bus types are still responsible for their own MODALIAS properties. Boot tested on ARM and compile tested on PowerPC and SPARC.
