soc/intel/alderlake: skip external buses for D-states list

The devices in the list that was introduced in commit c66ea985776
("soc/intel/alderlake: provide a list of D-states to enter
LPM") are all internal. This CL skips the external buses (which caused
the addition of packages to non-existant paths such as
"_SB.PCI0.RP1.MCHC", and warnings from the kernel)
