-Snubber circuit under ecrtail load condition can dissipate more power
then the resistor can handle, increased the resistor size and added one
more in parallel
-Increased size of some of the 12V input capacitors
-Use 3.3Vp instead of 3.3V generated by the RPi for LED, RTC, Radio, Fan
control and RPi reduced hat connector
-PoE pri/sec capacitor value changed

decreased coupling between poe lines and the gnd plane
added vias to stich main gnd planes
decreased the peak current through the transformer
inductor based pi filter on the poe output
decreased coupling to gnd of the poe "noise path"
added parallel mosfet capacitance to poe
moved fb line fo the dcdcs away from inductors

Increment to sub-version v1.2. Main changes are:
- Back and front silk screen
- LED resistors
There are no changes in the layout and any critical components.

Switch the SiLabs Radio module from MGM210PB32JIA2 to MGM210PA32JIA2.
The PA version has no secure vault but is slightly cheaper. It is
unlikely that we use the secure vault anytime soon, so let's use the PA
version.

Adjust some high level placement like M.2 or CM4 and heatsink. Remove
all traces and vias since most of the layouting has to be redone
anyways.

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.

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.

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

Make sure property ids are unique within a symbol. This should avoid
