docs: powerpc: convert docs to ReST and rename to *.rst Convert docs to ReST and add them to the arch-specific book. The conversion here was trivial, as almost every file there was already using an elegant format close to ReST standard. The changes were mostly to mark literal blocks and add a few missing section title identifiers. One note with regards to "--": on Sphinx, this can't be used to identify a list, as it will format it badly. This can be used, however, to identify a long hyphen - and "---" is an even longer one. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

==========================
powerpc: Add some documentation of ISA versions Add some documentation on which CPU versions map to which ISA versions. This is all publicly available information, some of it already in the kernel source, but it's much nicer to have it all in one place. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
