Subject: [PATCH -next] of/platform: Fix sparc:allmodconfig build

sparc:allmodconfig fails to build with:

drivers/built-in.o: In function `platform_bus_init':
(.init.text+0x3684): undefined reference to `of_platform_register_reconfig_notifier'

of_platform_register_reconfig_notifier is only declared if both OF_ADDRESS
and OF_DYNAMIC are configured. Yet, the include file only declares a dummy
function if OF_DYNAMIC is not configured. The sparc architecture does not
configure OF_ADDRESS, but does configure OF_DYNAMIC, causing above error.

Fixes: 801d728c10db ("of/reconfig: Add OF_DYNAMIC notifier for platform_bus_type")
