- Change FL1 to be Murata Electronics DLW5BTM102SQ2. This version is not
automotive approved. It is cheaper and has better availability
currently.

Replace the HRO part with the XKB part. The HRO part had shorter feet
which caused issues during soldering.

Add BD9D321EFJ to the symbol library and align it properly to the
1.27mm/0.050inch grid. Make sure to align the instances U15/U16
correctly as well as the complete Power schematic.
With that GND is now correctly connected to Pin 5 of U16.

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.

Deal with DRC warnings by either ignoring (like courtyard overlap of
fiducials) or fixing (removing duplicate vias).
Also use a shorter route for SWDIO.
