Bug Description

Need to enable intel_idle for the Elkhart Lake product line in mainline kernel.

This allows for finer-grain C-state control (using all supported platform MWAIT hints) than ACPI C-states. The intel_idle driver uses a different approach (MWAIT calls from kernel driver) than Windows (ACPI calls from kernel driver).

Target Release: 20.10
Target Kernel: 5.6
