[PATCH v2 15/16] memory: stub out request_barebox_region for PBL

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

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.
