Caravel 2nd phase (branch phase2): First pass at removing the analog
signals left over from Raven/Ravenna but not used on StriVe. Reduced
the GPIO for the management area to 2 bits. Removed additional unused
signals, removed the controls to the deleted analog signals, and
reduced the remaining controls. Renamed the digital libraries for
the sky130 Google/SkyWater naming conventions. Work in progress; much
more left to do.
