soc/intel/alderlake: Add missing min sleep state for DPTF device

Add an entry in the min_pci_sleep_states array for SA_DEVFN_DPTF,
to correct warning in cbmem log:
[WARN] unknown min d_state for PCI device 00:04.0

TEST=build/boot google/brya (banshee), verify warning not present in
cbmem log, verify entry for DPTF device in ACPI LPI constraint list.
