of/address: merge of_iomap() Merge common code between Microblaze and PowerPC. This patch creates new of_address.h and address.c files to containing address translation and mapping routines.

of/address: Merge all of the bus translation code Microblaze and PowerPC share a large chunk of code for translating OF device tree data into usable addresses. Differences between the two consist of cosmetic differences, and the addition of dma-ranges support code to powerpc but not microblaze. This patch moves the powerpc version into common code and applies many of the cosmetic (non-functional) changes from the microblaze version.

of/address: merge of_address_to_resource() Merge common code between PowerPC and Microblaze. This patch also moves the prototype of pci_address_to_pio() out of pci-bridge.h and into prom.h because the only user of pci_address_to_pio() is of_address_to_resource().
