fwk: azalea: should reset the diagnostic when power on the system

EC should reset the diagnostic wheh pressing the power button to power
on the system. The current EC code only resets the diagnostic when the
chipset state in G3.
This change adds the condition to reset the diagnostic if the chipset
state is S5.
