[PATCH 3/3] Documentation: powerpc: add elf_hwcaps to table of contents

[Bagas Sanjaya]

elf_hwcaps documentation is missing from table of contents at index.rst,
hence triggers Sphinx warning:

Documentation/powerpc/elf_hwcaps.rst: WARNING: document isn't included in any toctree

Add the documentation to the index to fix the warning.
