CST: remove AT%Nxxxx old AEC control
This crude method of enabling and configuring AEC is not compatible
with L1_NEW_AEC, and even for the old AEC it did not support every
possible combination. It is time for this hack to go. The new and
proper way of enabling and configuring AEC is via RiViera Audio Service
audio mode facility, either audio mode files or full access write,
most directly accessible via fc-tmsh auw 12 for free experimentation.

FC Tourmaline stdmodem functional configuration is equivalent to Magnetite hybrid. The only intentional diff from Magnetite to Tourmaline in the modem configuration is the change of Nucleus: Magnetite uses the blob version of Nucleus which came with TCS211-20070608, whereas Tourmaline uses the source version of Nucleus by Comrade XVilka. It is essentially a change from an unknown version of Nucleus to a known one, thus it should generally be considered an improvement - but as always with such changes, extensive verification and testing needs to be done in order to ensure that nothing got broken. Aside from the one intentional change of Nucleus version, FC Tourmaline is an entirely new firmware source tree, thus it is always possible that something could have got broken unintentionally, particularly in rarely-tested areas of the firmware. Therefore, extensive testing will need to be done before we can declare Tourmaline stdmodem as officially replacing Magnetite hybrid for stable modem products.
