[PATCH v2 11/16] of: stub out live tree API when using PBL

[Ahmad Fatoum]

To optimize out calls to undefined functions in PBL at compile-time
instead of link time, let's define stubs for the functions that
are referenced in obj-pbl-y files, but inside function sections
that are ultimately unreferenced.
