c7340505c8 Use impedance for JLC7628 stackup/switch HDMI/SW2 placement
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.

- 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

513bd69bf3 Redesign buttons/switches
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.

Fixes: #16
