ACPI: bus: Indicate support for _TFP thru _OSC
The ACPI thermal driver already uses the _TPF ACPI method to retrieve
precise sampling time values, but this is not reported thru _OSC.
Fix this by setting bit 9 ("Fast Thermal Sampling support") when
evaluating _OSC.
Fixes: a2ee7581afd5 ("ACPI: thermal: Add Thermal fast Sampling Period (_TFP) support")
