This looks wrong. Unfortunately until we get kernel.org back its hard to
do much about it and see what is in all the trees.

This breaks Medfield so NAK
The correct behaviour should be
INTEL_MID defined -> mrst_cpu_chip has meaning
INTEL_MID not defined -> mrst_identify_chip is 0
your change makes it 0 for Medfield which means it will crash on boot.
