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 Change-Id: I0463236996ad001af506c9966840b27fe44d60d2 Signed-off-by: Sumeet R Pawnikar <sumeet.r.pawnikar@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/45454 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org>
