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.
