- 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 through hole 3.5mm Audio jack to make sure it does nto get teared
off the board accidentially that easily.

Make sure those signals are well defined even when not be driven from
the CM4 side. Also rename Radio.BOOT to Radio.~BOOT since its a low
active signal.

Use the correct footprint for the PoE bulk capacitor C80. The TI
evaluation module circuit uses a Panasonic EEE-FK1J470P bulk capacitor.
The series has other better suited alternatives like EEE-HA1J470UP, but
the F-size code seems to be a sensible choice.

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.

changes:
-more routing
-added poe negotiation disabled when +12V is present on the DC jack

The 1- at the start of the part number denotes M-Key which is a rather
important distinction. Fix the footprint name.

We don't plan to populate those connectors by default. The through-hole
ones are easier to solder by hand on a populated PCB.
