intel/apollolake: Add soc specific DPTF values
This patch adds apollolake soc specific change. DPTF ASL files are now in src/soc/intel/common so that they can be reused but different soc can have different values e.g., for skylake cpu soc thermal reporting device is at Bus 0, Device 4, Function 0 while for apollolake it is Bus 0, Device 0, Function 1. This patch adds a dptf asl file in soc directory where we can define all values which can change across soc's and can be included in mainboard dptf asl. BUG=chrome-os-partner:53096 TEST=In Amenia and Reef board verify that the thermal zones are enumerated under /sys/class/thermal in Amenia and Reef board. Navigate to /sys/class/thermal, and verify that a thermal zone of type TCPU exists there.
