schematic: mark R22 as dot no place

R22 is use to pull the FLAGB output of the FPF2109 high since this
is an open-drain output.
but we actually don't read FLAGB do get the error conditions, thus
thus pull-up resistor is not required.

this change has been tested with a real simtrace device....

schematic: mark R24 as no place

R24 is pulling the voltage regulator output for VCC_SIM down.
it has probably been added at the same time as R15.
since we don't read VCC_SIM it is not important to have it in a
defined state.
also the card, phone, or simtrace will provide power to the card...

schematic: mark R15 as no place

R15 is pulling VCC_SIM down.
it has probably been added because a load resistor is present in
the FPF2109 datasheet example application, or to not have VCC_SIM
in tri-state.
since we don't read VCC_SIM it is not important to have it in a...

schematic: make it more readable

- VCC is up
- GND is down
- group the parts by functionality and use net name
- separate decoupling capacitors
- arrange groups from left input to right output

updated libraries to KiCad 5

the library system changed from KiCad 4 to KiCad 5.
the custom libraries have been re-added to the project, and all
symbol names have been updated.
some symbols are a bit smaller, requiring to add some wires.
