I am leaning to leave the PCI stuff alone for now. If we change the PCI 
definitions I'd like to do it on the SKL and legacy sides at the same 
time, to avoid multiple definitions or redundancies.

However I like your suggestion for the macros on the other patch so will 
change the code.

Thanks for the reviews!
