xpp: support loading Octasic EC firmware

Echo Cancellation firmware is loaded by xpp/stribank_hexload
(Using the oct612x code).

* astribank_hexload: options -O/-o/-A for handling the Octasic echo
  cancellation firmware.
* astribank_tool: report that.
* xpp_fxloader: Run astribank_hexload, if needed.
* dahdi_perl: The EC module is an extra XPD, but not a "telephony device"
  and hence not a span. Deal with that.
* waitfor_xpds: may need to wait a bit longer for firmware loading.
