Use JLC7628 impedance values to get more options in color selection.
Also this leads to slightly wider traces typically, and it will be
easier to switch back to JLC2313 or the like than the other way around.
Also swap placing of HDMI/SW2 and rotate the heatsink by 90° for easier
routing.

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.

Instead of using VBUS to power CP2102N use the main/NVMe 3.3V supply.
This makes sure that the device stays powered during reset, while making
sure the CP2102N is always powered and doesn't backfeed if no USB is
plugged in.

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.
