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.
