Subject: powerpc: Align TOC to 256 bytes

From: Anton Blanchard <anton@samba.org>

commit 5e95235ccd5442d4a4fe11ec4eb99ba1b7959368 upstream.

Recent toolchains force the TOC to be 256 byte aligned. We need
to enforce this alignment in our linker script, otherwise pointers
to our TOC variables (__toc_start, __prom_init_toc_start) could
be incorrect.

If they are bad, we die a few hundred instructions into boot.
