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.

pcb: sch: make ICE40 VCCPLL a power input
...
For some reason, this pin was listed as a `power output`, which does not
appear to be the case. Due to this error, the DRC would fail when using
a regulator directly connected to the pin.
Mark this pin as a `power input` to fix this, since it's really where
power goes into the chip.
