Subject: [PATCH] res_pjsip: Document 'none' option for 'dtmf_mode'.

The 'none' value can be used to disable DSP processing for DTMF
on PJSIP channels and is sometimes necessary for this reason,
and already exists in the code, but is not documented. Add it to
the documentation enum.

Resolves: #2026
