- Replace unusual/high value ceramics with lower value in parallel
- Use the same protection Shottky Diode in PoE as in regular input
(B340LB-13-F)
- Replace PoE rectifier Diodes with B1100-13-F
- Replace PoE Inductor (SRN6045TA-3R3Y) with the same part from 5V power
supply (Taiyo Yuden NRS8030T3R3MJGJ)
- Correctly specify Pulse Electronics transformer

Remove power/reset/recovery switch. Power and reset is not really required
and recovery mode (USB Boot) can be triggered via jumper. Make the Fan
and RPiLED a new separate config so we can leave them unpopulated. Add a
second GPIO controlled switch.

Use a jumper instead of a switch to change between CM4 USB Device and
CP2102N. Replace CP2102N QFN24 with QFN20 variant. Make CP2102N to be
bus-powered by default.

CRFILT capacitor is required for the chip to start properly
and 10k pull-downs were too strong according to the datasheet.

Add the CM4 board to board connectors using separate symbols. This is a
bit a hack, but makes sure two pieces appear in the BOM.
Also, this seems to upgrade all the schematic to the latest KiCad
schematic version.
