commit 65c0c2367e9e695b13d0d39307ebc8818bcdbd8d Author: Zhang Rui rui.zhang@intel.com Date: Tue Sep 20 20:58:48 2022 +0800

intel_idle: Add AlderLake-N support

Similar to the other other AlderLake platforms, the C1 and C1E states on
ADL-N are mutually exclusive. Only one of them can be enabled at a time.

C1E is preferred on ADL-N for better energy efficiency.

C6S is also supported on this platform. Its latency is far bigger than
C6, but really close to C8 (PC8), thus it is not exposed as a separate
state.
