Subject: [PATCH] ACPI: ACPI thermal zone handle notification correctly

Change the ACPI thermal action upon notification 0x81 and 0x82.

According to the ACPI spec, we should:
re-evaluate _PSV and _ACx methods upon notification 0x81
re-evaluate _PSL and _ALx and _TZD upon notificaiton 0x82.
But the current code re-evaluates all the trip points for 0x81 while
only re-evaluates _TZD for 0x82.

Fix this violation of ACPI spec.

TODO: devices in _PSL, _ALx and _TZD may change after a notification 0x82.
      At this time, we need to re-bind the cooling devices with the thermal zone.
