cpu/x86: add pae paging module to all stages
In preparation for bringing in paging early always provide the paging pae module to all stages. Since we cull unused symbols this is a no-op. Compilation testing will happen all the time since the module currently doesn't compile without <arch/cpu.h> include. The current file is completely guarded with ENV_RAMSTAGE because it's using cpu_index() which is a ramstage-only construct.
