schematic: add DNP note on JTAG and UART debug connectors

Change-Id: Id1c03418af021ce8febd666946bed3d8c01ceb77

schematic: mark USB reset circuit as dot no place

the additional circuit to reset USB (by pulling D+ low) is not
required anymore since the USB controller in the SAM3S integrates
this capability.
the SAM3S-EK Development Board also demonstrates only the inline...

schematic: mark R19 as dot no place

R19 pulls VCC_PHONE low for better power on detection.
but the voltage divider R20 + R21 also pull this line low using
a stronger pull down resistor ok 20 kOhm.
thus R19 is unnecessary-

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

schematic: rename NP to DNP for clarity

schematic: mark JP1 and JP2 as dot no place

the protruding through hole pins of the header for the jumper
might get shorted when the board lies on a conductive surface,
leading to unwanted flash erase (JP2) or false TST signal (JP1)

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.
