device property: export code duplicating array of property entries
When augmenting ACPI-enumerated devices with additional property data based on DMI info, a module has often several potential property sets, with only one being active on a given box. In order to save memory it should be possible to mark everything and __initdata or __initconst, execute DMI match early, and duplicate relevant properties. Then kernel will discard the rest of them.
