ddb_template: edge counter keys correspond with according ttl keys 

previously ttl_counter_0 and ttl_0 could be on completely different physical ttl output channels
with this change, ttl_0_counter (note the changed key format) is always on the same channel as ttl_0

* ``get()``, ``get_mu()``, ``get_att()``, and ``get_att_mu()`` functions added for AD9910 and AD9912
* New hardware support:
- HVAMP_8CH 8 channel HV amplifier for Fastino / Zotino
* ``artiq_ddb_template`` generates edge-counter keys that start with the key of the corresponding
TTL device (e.g. ``"ttl_0_counter"`` for the edge counter on TTL device``"ttl_0"``)
