alpha: Clean up linker script using new linker script macros.

Note that .data.page_aligned and .data.cacheline_aligned are now after
_data; it was probably a bug that they were before it.

Also, some explicit ALIGN(8)'s between various initcall sections were
removed; this should be harmless as the implicit alignment of
initcall_t was already 8.
