OF: import address related functions from Linux OF API
This imports drivers/of/address.c from Linux with some minor modifications.
of_translate_address is not yet enabled and PCI and ISA related bus translations
have not been imported. Also, a corresponding include header is created with
prototypes and non-OF function stubs.
