temp_metrics: disable ACPI thermal zone 1
ACPI thermal zone 0 is used for critical thermal events while thermal zone 1
is used for asserting (internal) prochot and duty cycling. Since the
equivalent of thermal zone 1 functionality exists in temp_metrics,
disable ACPI's thermal zone 1 in order to prevent conflicts between ACPI
and temp_metrics.
BUG=chrome-os-partner:9193
TEST='cat /sys/class/thermal/thermal_zone1/mode' and check that it is
disabled.
