Add explicit #define for bogus temp override

Browse Source 
The code to ignore the "bad thermistor reading failsafe"
suicide function depends on the existing of the PS_ON pin
feature.  But in some boards this shouldn't be the case
Fix this by adding an explicit definition to make our
intentions more clear and separable.
