soc/intel/alderlake: Inform user during CSE update

If a CSE update is going to happen and early graphics is supported by
the mainboard, an on-screen text message is displayed to inform the
end user.

CSE update can take a while and an impatient end user facing a black
screen for a while may reset the device unnecessarily.
