We are having build failure with linux-next for sparc allmodconfig with
the error messages:
undefined reference to 'of_io_request_and_map'
CONFIG_OF is defined for sparc so it is expected that we have a
definition of of_io_request_and_map() but of/address.c is only compiled
if it is !SPARC. In other words, CONFIG_OF_ADDRESS is not defined for
sparc so we get the build failure.

v1: had a complicated set of #ifdefs
v2: i messed up and resulted in build failure of some other arch where
CONFIG_OF is not defined.
v3: tested with allmodconfig of x86_64, defconfig of alpha and mips.
