soc/intel/jasperlake: Enable processor thermal control using PCI_DEVFN
Enable processor thermal control using PCI dev path function instead of
Device4Enable parameter in devicetree. This change removes the dependency
on Device4Enable in devicetree. We can enable and disable this thermal
control using on and off support with PCI device entry in devicetree.
BRANCH=None
BUG=None
TEST=Built and tested on dedede board
