Entering deep sleep breaks USB JTAG

It looks like stalling the cpu (e.g. by esp-backtrace's halt-cores) can trigger the same issue.

Current state: replugging USB fixes JTAG for that power cycle.

It should be possible to not power down JTAG and related stuff if the board goes to sleep while plugged in/connected.
