Ticket #207 (closed defect: wontfix)
DFU mode should only be enabled when in "911 key" mode

In order to minimize the security threat posed by DFU mode (everyone can just
read or write to all of the phone flash!), we should make sure that it is only
enabled in the "911 key" bootup mode, i.e. when both 911 and power buttons are
pressed at system start.
This is still no real protection, though. Unfortunately the USB DFU spec
doesn't provide for any authentication mechanism, so we will just stay with the
standard for now.
