Subject: [PATCH V6 02/13] of: platform: Make of_platform_bus_create() global

The boot constraints core needs to create platform or AMBA devices
corresponding to a compatible string and not for rest of the nodes in
DT. of_platform_bus_create() fits in the best to achieve that.

Allow it to be used outside of platform.c.

V6:
- Build bot reported a compilation error when CONFIG_OF_ADDRESS isn't
  selected in .config.
- Git didn't catch the change in the file when I rebased the patches to
  the latest kernel and applied this patch cleanly and so I missed that
  the function declaration is placed outside of the #ifdef/endif block.
- This patch just moves the declaration within the CONFIG_OF_ADDRESS
  block.
