[PATCH 5/8] powerpc: use new macro for .data.cacheline_aligned section.

.data.cacheline_aligned should not need a separate output section;
this change moves it into the .data section.

Since there isn't an ALIGN() directive before the
.data.cacheline_aligned scetion in the current linker script, I'd like
an ack from one of the powerpc maintainers that L1_CACHE_BYTES is the
correct alignment here.
