(cherry picked from commit 052c9599)

We always set primaryconsole in our images, which is enough
for the code to figure out that serial was enabled.  If a
user changed this, he will have to reconfigure to get the
expected result: primaryconsole set to something different
other than serial and secondaryconsole not set will obviously
not be enogh of a hint for a system to use the serial one.

This adds the "normal" power state to the powerd - system_advanced_misc options.
If the powerd utillity can not determine the system power options (ac or battery) it will use the "normal" setting rendering the "ac" and "battery" settings useless for these systems.
