PME_Status
This bit is set when the function would normally assert the PME# signal
independent of the state of the PME_En bit. Writing a “1” to this bit will
clear it.
This bit defaults to “0” if the function does not support PME# generation
from D3(cold).
If the function supports PME# from D3(cold) then this bit is sticky and
must be explicitly cleared by the operating system each time the
operating system is initially loaded.
