[PATCH v2 10/13] x86/cpu: Enable SD_ASYM_PACKING for DIE Domain on AMD Processors

[Mario Limonciello]

From: Perry Yuan <perry.yuan@xxxxxxx>

Enable the SD_ASYM_PACKING domain flag for the DIE domain on AMD
heterogeneous processors.
This flag is beneficial for processors with one or more CCDs and
relies on x86_sched_itmt_flags().
