gsm0808: add function gsm0808_speech_codec_from_chan_type()
The contents of the speech codec element (struct gsm0808_speech_codec),
that is also used in the speech codec list element (struct
gsm0808_speech_codec_list) can be generated directly from the
permitted speech parameter in the channel type field (struct
gsm0808_channel_type) when full AoIP with compressed speech via
RTP/UDP/IP is assumed and when the codec configuration on the air
interface exactly matches the codec configuration on the IP backhaul.
This patch adds a function that can be used as a helper to fill
out spech codec fields by only giving a permitted speech parameter
as input.
