powerpc/powernv: Fix OPAL debug entry
OPAL provides the firmware base/entry in registers at boot time for debugging purposes. We had a bug in the code trying to stash these into the appropriate kernel globals (a line of code was probably dropped by accident back when this was merged) Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
