gsm0808_utils: fix gsm48 multirate configuration generator
The function gsm0808_sc_cfg_from_gsm48_mr_cfg() takes an S15 to S0
bitmask and converts that bitmask into an AMR multirate configuration
struct.
Unfortunately the current implementation implements 3GPP TS 28.062,
Table 7.11.3.1.3-2 wrongly in some aspects. Lets fix this.
- Fix wrong interpretation of the bitpatterns
- 5,15K is invalid and must never be selected
- Make sure that no more than 4 rates are selected in the active set
- Extend unit-test
