docs: cdrom: convert docs to ReST and rename to *.rst 

The stuff there is almost already at ReST format. A
conversion for them is trivial: just add a missing titles
and fix some scape codes for them to match ReST syntax.

While here, rename the cdrom-standard.txt, with was converted
from LaTeX to ReST on the previous patch, and add it to the
index file.

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.

The ide-cd driver should work with all ATAPI ver 1.2 to ATAPI 2.6 compliant
CDROM drives which attach to an IDE interface. Note that some CDROM vendors
(including Mitsumi, Sony, Creative, Aztech, and Goldstar) have made
both ATAPI-compliant drives and drives which use a proprietary

this driver will not work with it (but one of the other CDROM drivers
probably will). This driver will not work with `ATAPI' drives which
