Add a method to convert from 1/10 Kelvin to Celsius. This
is useful for EC devices where the sensor temperature are
stored in Celsius instead of Kelvin.

In order to support using the common ACPI code on more platforms
than just Apollo Lake the DPTF code needs to be told what the
PCI address is for the CPU thermal device.

Currently the thermal event handler method TEVT is defined as an extern,
then defined again in platforms with thermal event handling. In newer
versions of IASL, this generates an error, as the method is defined in
two places. Simply removing the extern causes the call to it to fail on
platforms where it isn't actually defined, so add a preprocessor define
where it's implemented, and only call the method on those platforms.

In _FSL ACPI notification 0x83 was incorrectly being sent to DPTF.
When there should be no notification on fan speed change.

This patch adds the common ASL code for Intel
platforms. This is the basic ASL needed to add support
for DPTF controlled devices. We are moving
these commmon ASL files to src/soc/intel/common/acpi as
these are same codes used in all Intel platforms and
hence no need to duplicate.
BUG=chrome-os-partner:53096
TEST=Verify that the thermal zones are enumerated
under /sys/class/thermal. Navigate to
/sys/class/thermal, and verify that a thermal
zone of type TCPU exists there.
