thermal: intel_pch_thermal: constify pci_device_id.

ArvindYadavCs · zhang-rui · commit 9b877de3e055 · 2017-08-08T21:31:43.000+08:00
pci_device_id are not supposed to change at runtime. All functions
working with pci_device_id provided by &lt;linux/pci.h&gt; work with
const pci_device_id. So mark the non-const structs as const.
