chrome ec: Fix temperature calcualtion in PATx methods
The PATx methods will be passed a temperature in deci-kelvin,
so it needs to be converted back to kelvin before being sent
to the EC.
The PAT disable method is changed to take the temperature ID
as an argument so individual sensors can be disabled.
BUG=chrome-os-partner:17279
BRANCH=rambi
TEST=build and boot on rambi, load esif_lf kernel drivers and
esif_uf userspace application. Start and stop DPTF and see
that temperature thresholds are set to sane values.
