kernel-doc: describe the `literal` syntax

Browse Source 
changeset b97f193abf ("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.

``%CONST``
Name of a constant. (No cross-referencing, just formatting.)
````literal````
A literal block that should be handled as-is. The output will use a
``monospaced font``.
Useful if you need to use special characters that would otherwise have some
meaning either by kernel-doc script of by reStructuredText.
This is particularly useful if you need to use things like ``%ph`` inside
a function description.
``$ENVVAR``
Name of an environment variable. (No cross-referencing, just formatting.)
