if C3 does not work, this needs to be fixed in the code that implements
C3, not in the code that selects C3.


Modern systems should have working C3; if one does not it needs to be
investigated as to why it's not working. One cause could be a PME that
we're not handling (I've seen that a few times in our lab), lspci -vvv
will show that.

But regardless, it's not the task of the code that selects a C state to
deal with....
