of: Provide static inline function for of_translate_address if needed
If OF_ADDRESS is not configured, builds can fail with errors such as
drivers/net/ethernet/hisilicon/hns_mdio.c:
In function 'hns_mdio_bus_name':
drivers/net/ethernet/hisilicon/hns_mdio.c:411:3:
error: implicit declaration of function 'of_translate_address'
as currently seen when building sparc:allmodconfig.
Introduce a static inline function if OF_ADDRESS is not configured to fix
the build failure. Return OF_BAD_ADDR in this case. For this to work, the
definition of OF_BAD_ADDR has to be moved outside CONFIG_OF conditional
code.
