From: Frank Rowand <frank.rowand@sony.com>
Remove "phandle" and "linux,phandle" properties from the internal device tree. The phandle will still be in the struct device_node phandle field and will still be displayed as if it is a property in /proc/device_tree.
This is to resolve the issue found by Stephen Boyd [1] when he changed the type of struct property.value from void * to const void *. As a result of the type change, the overlay code had compile errors where the resolver updates phandle values.

Patch 1 is the phandle related changes.
Patches 2 - 4 are minor fixups for issues that became visible while implementing patch 1.
Changes from v5: - patch 1: populate_properties(), prop_is_phandle was declared at the wrong scope and thus was initialized before the for loop instead of each time through the loop. This resulted in any property in a node after the phandle property not being unflattened.
Changes from v4: - rebase on 4.12-rc1 - Add reason for "<NULL>" in of_attach_node() - Simplify and consolidate phandle detection logic in populate_properties(). This results in a change of behaviour, the value of property "ibm,phandle" will no longer override the value of properties "phandle" and "linux,phandle".
Changes from v3: - patch 1: fix incorrect variable name in __of_add_phandle_sysfs(). Problem was reported by the kbuild test robot
Changes from v2: - patch 1: Remove check in __of_add_phandle_sysfs() that would not add a sysfs entry if IS_ENABLED(CONFIG_PPC_PSERIES)
Changes from v1: - Remove phandle properties in of_attach_node(), before attaching the node to the live tree. - Add the phandle sysfs entry for the node in of_attach_node(). - When creating an overlay changeset, duplicate the node phandle in __of_node_dup().
