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

It's much cleaner if we put power pins on one side and signal pins on
the other. This removes the ratsnest that was building up.

hardware: sch: add crystal, VCCPLL regulator

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.

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.
