[PATCH 1/2] powerpc/vmlinux.lds: Move _edata down

Currently _edata does not include several data sections, this causes
the kernel's report of memory usage at boot to not match reality, and
also prevents kmemleak from working - because it scan between _sdata
and _edata for pointers to allocated memory.

This mirrors a similar change made recently to the x86 linker script.

Lightly tested, doesn't crash the kernel, leak reports appear
to be mostly sane.
