Sylvain Munaut 5e86047024 fw/icE1usb: Update to support production hardware 
Also default build to it since very few people would want to build
firmware targetted to the prototypes ...

Sylvain Munaut c1d117b6de gateware/firmware: Match rx/tx tick order in register with doc 
The documentation always had the rRX tick in the LSB which
is consistent with having the RX units before TX.

They can be read as 16 bit value anyway so there isn't any
performance impact.

Sylvain Munaut f5d7bf2480 fw/e1-tracer: Import firmware for the E1 tracer board 
Some more code could probably be unified with the "normal" usb E1 adapter
to both reduce code duplication but also offer 'sniff' function to the
E1 adapter.
