platform/x86: thinkpad_acpi: silence HKEY 0x6032, 0x60f0, 0x6030

Demote to debug level one existing thermal-control related event, and
also add two new ones that would otherwise trigger unknown event
warnings.  These events are Windows-only for now.

We do report them to userspace in case they become useful in the future.
