this doesn't protect against malicious tampering (because
the public key is the developer key) but it will at least
catch correctness errors in USB upload and filesystem

try to improve the pmic detection code
...
we can now recover from an I2C timeout and get the PMIC data
out, but mysteriously, when we leave the routine, the CPU hangs.
I think fundamentally the I2C instability is due to something
very wonky inside the chip itself, so the recovery only papers
over an issue that is only fixed with a reboot...

clean up some gross static mut state stuff
...
still have to resolve the static mut issue of getting the USB
controller state into the interrupt controller.
I'm not sure there *is* a good way to do it - this might actually
be "the" use case for static mut's - but the point of this
exercise was to just diff out the driver in machine mode versus
OS mode to try and figure out if there's a hardware problem
causing instability or if it's a driver issue
the conclusion so far is that the USB stack requires extremely
tight interrupt handling timing, and so, for better stability
we may have to mirgate away from the heavily user-space dependent
implementation currently in use.

disk enumerates now, and initiates r/w transactions but
the reference driver does not match the implementation in that
