Update EC commit, gpio monitoring fix

Previously, HyperDebug could get confused, if "transport init" was run
while there were GPIO monitoring in progress, typically because a test
failed or was interrupted before completing.

This would lead into a status where HyperDebug responded correctly, but
never recorded any more edge detections, until it was reset.

Also, a Google extension to the CMSIS-DAP protocol for advertising
support for other extensions was not properly implemented.  (And has not
yet been used by opentitantool.)
