mpcie-breakout: change 100uF caps from 1210 to 1206, reducing height
...
The current 100uF caps are too high at 2.9mm. They touch the shielding
can of Quectel EC-20 modules, for exampel. Let's use 1206 packaged
versions at 1.6mm instead. Also, add two more, for safety.

WIP: design for a multi-voltage USB UART
...
* an adjustible LDO with rotary switch is able to configure the UART
voltage levels as needed.
* alternatively, the UART logic level voltage (in the 1.8-3.3V range)
can be provided by an external voltage reference.
* TVS diodes protect the USB and UART sides from overvoltage and ESD
* all voltages are available on a header to supply external circuitry
* five GPIO pins are available on a header
