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. Change-Id: I257c972e9fdf0dfe940a8d483447085bd62e50a2
