baytrail: Updates for DPTF ACPI framework
- Remove some unused functions from CPU participant that were confusing the userland component since the CPU does not have an ACPI managed sensor. - Guard the charger participant with an ifdef so it can be left out if not supported. - Use the EC methods for setting auxiliary trip points and for handling the event when those trip points are crossed. - Add _NTT _DTI _SCP methods for thermal sensors. I'm not clear if these are required or not but they seem to be expected by the other DPTF framework components.
