mcu: Contact and identify all the mcus prior to configuring them

Break up the connect phase into two phases - mcu_identify and connect.
The first phase will contact all the micro-controllers and obtain the
"identify" data dictionaries for them.  Once all the micro-controllers
have been contacted, then they can be configured.  This fixes an issue
with FIRMWARE_RESTART not working correctly on multi-mcu setups that
use restart_method=command.
