of/address: sparc: Declare of_iomap as an extern function for sparc again
This bug-fix makes sure that of_iomap is defined extern for sparc so that the sparc-specific implementation of_iomap is once again used when including include/linux/of_address.h in a sparc context. OF_GPIO that is now available for sparc relies on this. The bug was inadvertently introduced in a850a75, "of/address: add empty static inlines for !CONFIG_OF", that added a static dummy inline for of_iomap when !CONFIG_OF_ADDRESS. However, CONFIG_OF_ADDRESS is never defined for sparc, but there is a sparc-specific implementation /arch/sparc/kernel/of_device_common.c. This fix takes the same approach as 0bce04b that solved the equivalent problem for of_address_to_resource.
