mm/init-mm: export init_mm struct

Export init_mm struct to resolve dynamic linking issue while
inserting the kernel module having details related to init_mm.
Module insertion failed if we don't export init_mm and following
error msgs are seen while inserting the kernel module:
- failed to load /system/lib/modules/pte_validate.ko: No such file
  or directory
- UART: Unknown symbol init_mm (err 0)
