ACPI: thinkpad-acpi: make sure DSDT TMPx readings don't return +128
We get +128 instead of -128 from the DSDT TMPx methods, due to errors when
converting a EC byte return that is a s8 to an ACPI handler return that is
an int.
Fix it once and for all, by clamping acceptable temperature readings from
DSDT TMPx so that anything outside the [-127,+127] range is converted to
TP_EC_THERMAL_TMP_NA (-128).
