I know what is happening here.

The chip is powered OK, but while wlan0 is "down" the wifi reset is
also held low (necessary for proper reset).
And unfortunately the wifi reset is tied to the BT reset.  Oops.

This might be messy to fix.

If future boards could have separate GPIOs for these two reset lines, that
would be good.
