Subject: of-graph: export symbol of_phandle_iterator_init/next
Git-commit: 00bab23f72100a5fd8a3030f81d0af07a859ed17
Patch-mainline: v4.13-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

of_for_each_phandle() uses of_phandle_iterator_init/next
but it isn't exported. So kernel module complile will say

ERROR: "of_phandle_iterator_init" [xxx.ko] undefined!
ERROR: "of_phandle_iterator_next" [xxx.ko] undefined!

This patch solved this issue
