| Test on R1721 (0R). maybe make this 1R / 10R for test purposes

| If we see current spike on this PMU-power-out, the current-limiter is
crap,

Good idea and I will try it, but reworking these 0402s that are glued
down somehow is very risky for me.

I managed to repair the victims of the last rework attempt to remove
C1707, with this 47u gone from IO_3V3 the effect is that IO_3V3 rises
much faster (still linearly) but it still fails to boot.  Because it
rises faster compared to 47u being present, it puts a limit on how low
the remaining impedence on IO_3V3 is it seems to me, but R1721 is still
worth doing.
