UPSTREAM: of: add HAS_IOMEM depends to OF_ADDRESS

On UML builds, of_address.c fails to compile:

../drivers/of/address.c:873:2: error: implicit declaration of function ‘ioremap’ [-Werror=implicit-function-declaration]

This is due to CONFIG_OF now being user selectable. Add a dependency on
HAS_IOMEM to OF_ADDRESS in order to fix this.
