We are having build failure with linux-next for sparc allmodconfig with
the error messages:
drivers/built-in.o: In function `meson6_timer_init':
meson6_timer.c:(.init.text+0x5fe8): undefined reference to `of_io_request_and_map'
drivers/built-in.o: In function `mtk_timer_init':
mtk_timer.c:(.init.text+0x6af0): undefined reference to `of_io_request_and_map'
drivers/built-in.o: In function `asm9260_timer_init':
asm9260_timer.c:(.init.text+0x6c48): 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.
