Yeah, FETs + MPU beat caps :-) Powering the MPU becomes a bit tricky,
though, since we can't use the secondary side of the PMU. We could
use VB_SYS, though.

We'll have to give that MPU one more try soonish. Oh, and look what
I found. I'm sure there's also someone who makes these same kind of
thing a little cheaper.

Cheers, Werner
