The current approach of using hardcoded values in 'platform_features' structure fails to effectively represent these divergences. To improve the description of platform divergence: 1. Each newly introduced 'platform_features' structure must have a base, typically derived from the previous generation. 2. Platform feature values should be inherited from the base structure rather than being hardcoded. This approach ensures a more accurate and maintainable representation of platform-specific features across different generations. Converts `adl_features` and `lnl_features` to follow this new scheme. No functional change.

This inconsistency is confusing and adds unnecessary code complexity. Consolidate the access method by opening the sysfs files once and reusing the file pointers for subsequent accesses. This approach simplifies the code and ensures a consistent method for accessing graphics sysfs knobs.

The current implementation does not handle this scenario, resulting in the loss of graphics C6 residency and frequency information. Add support for /sys/class/drm/card1, ensuring that turbostat can retrieve and display the graphics columns for these platforms.
