Move some vias around to get the 5V plane more breathing room. Add a
small pour to give more copper and stabilize the net.

pcb: remove usb silk, add more 5V vias
...
Add more 5V vias near the 1.2V regulator, and replace a manual trace
with a copper pour. This will increase the amount of copper going to
both the 3.3V and 1.2V regulators, which should improve stability.
While we're at it, remove an errant silk artifact on the USB connector.
