revC2: Swapped Micro USB for USB-C USB 2.0 connector.

This is the inital routing pass. This is the status after esden's Twitch
stream on Tuesday May 26th 2020.

revC2: Replaced HiZ with P- to better reflect the actual function.

The GPIO extenders can set a Pull-Up/-Down resistor or do nothing. That
is not the same thing as HiZ. HiZ is only true if the level shifters are
also set to input. So P- (Pull nothing or Passive) is a better term.

revC2: Align inline resistors and Sync level shifter.

They were not aligned in a vertical line. For aethetic reasons this is
now fixed. :)

revC2: Some minor silkscreen legend improvements.

Mainly improved readability of the Pull-Up/-Down control block legend.
This resulted in some of the passives being moved out of the way to make
space for the legend. Also added legend that indicates which level
shifter is responsible for which IO signal, including Sync.

revC2: Part ID removed from silkscreen, added logic block legends.

All part IDs and values are now meant to be printed on the Fab layer as
hardcopy manual assembly and population guide. The space on the
silkscreen used for part IDs was partly traded against logical circuit
block documentation. This is just the first pass and meant as a stepping
stone. The goal is to have the logical functionality be as self
descriptive on the silkscreen as possible.

revC2: Spread level shifters to respect courtyards.

As part of rerouting also moved half of the power via under the
packages. We regained some space thanks to that resulting in slightly
cleaner routing.
