dahdi-base: Remove old method of invoking HWEC
Remove the code that allowed hardware echo cancellation to automatically
override software cancellation and prevented SWEC from working at all on a
card if HWEC was installed. All EC now uses the standard modular EC interface.
Additionally, the "SWEC" identifier on channel lines in /proc/dahdi has been
changed to "ECTYPE" to avoid confusion.
