In order to implement flash support, as well as aid in maintenance situations, support for requesting the board to be powered on into EDL/flashing mode is useful. So far the payload of the MSG_POWER_ON message has been ignored by the server, so we can tread the absence of payload as "NORMAL" power on request and introduce the power_on_mode enumeration to define the values in this (optional) byte. A new key definition is also added to the protocol, representing the holding down the EDL "key", but not exposed on the client side yet. The device logic is wired up such that the power-on sequence will now request the drivers to hold the EDL key while powering on, if the power-on mode is "EDL".
