Removing comments relating to SSL fingerprinting for ESP8266 MCUs due to this notice.

This is probably worth actually testing, to see if it is possible still to connect to port 8883 with secure client but using the turn off security validation option (use insecure method or something similar).
It's the equivalent of saying users can no longer fetch web site stuff because https doesn't work, but in reality it can work with no cert validation.
