kernel-doc: describe the ``literal`` syntax
changeset b97f193abf83 ("scripts/kernel-doc: fix parser for apostrophes") added support for ``literal`` inside kernel-doc, in order to allow using the "%" symbol inside a literal block, as this is used at printk() description. Document it. Fixes: b97f193abf83 ("scripts/kernel-doc: fix parser for apostrophes") Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
