powerpc: Fix boot problem due to AT_BASE_PLATFORM change
Commit 9115d13453dee22473a1e8cacc90a8d64a9c4bc9 ("powerpc: Enable AT_BASE_PLATFORM aux vector") broke boot on 32-bit powerpc systems; we have to use PTRRELOC to initialize powerpc_base_platform this early in boot. Bug reported by Jon Smirl. Signed-off-by: Nathan Lynch <ntl@pobox.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
