soc/intel/cannonlake: Add missing entry to soc_acpi_name()

The device name for the SA thermal/DPTF PCI device was missing from
soc_acpi_name(), leading to an invalid PLI device constraint entry
being generated in the SSDT (the name field was blank/missing).
Add the missing entry, matching the name to the existing ACPI
device.

TEST=build/boot Win11 on google/puff (wyvern) without a BSOD.
