xpd_echo: XPP Octasic echo canceler module
* xpd_echo (card_echo.c) - a module to handle an Astribank hardware echo
canceller module.
* All other XPDs are now of type 'telephony_device'. Only a telephony device
XPD provides a span to register.
* The EC module will typically show up as XPD-40 and will always show up as
Unregistered in 'dahdi_hardware -v'
