[PATCH v2 02/15] scripts: kernel-doc: Transform documentation into POD (2/15)

["Tomasz Warniełło" <tomasz.warniello@gmail.com>]

Step 2) Add the SYNOPSIS section

Rst-only options are grouped around rst, the rest is arranged
as in the OPTIONS susections (yet to be translated into POD,
check at the end of the series).

See step 1 for the series details.
