ACPI: OSI: Stop advertising support for "3.0 _SCP Extensions"
As specified in section 5.7.2 of the ACPI specification the feature
group string "3.0 _SCP Extensions" implies that the operating system
evaluates the _SCP control method with additional parameters.
However the ACPI thermal driver evaluates the _SCP control method
without those additional parameters, conflicting with the above
feature group string advertised to the firmware thru _OSI.
Stop advertising support for this feature string to avoid confusing
the ACPI firmware.
