hardware: sch: first draft of dvt1
...
This removes much of the support debugging stuff from evt1. Still to
do:
- Assign footprints
- Figure out which PU resistor to include (if any)
- Figure out if we need to keep the USB buffering
- Remove extra decoupling caps

The PCB is terrible, and probably would have all sorts of issues. Will
rip it up and try again tomorrow.

We have spare pins, so run more debug wires.
Many of these will probably get cut when doing the PCB layout.

Add a crystal, so we can test to make sure it works.
Also add a second regulator dedicated to VCCPLL in an effort to
cost-down the capacitor and large components that shouldn't be
necessary.
