intel_x86: Report S0ix hang detected by EC using console print
This change prints out a warning indicating that S0ix hang is detected
by EC. This is very helpful when debugging S0ix issues to understand
when exactly the EC triggered the wake because of hang detect.
BUG=b:134781711
BRANCH=None
TEST=Verified on a system stuck before going into S0ix that EC prints
out the warning when waking host up because of hang detect.
