hwmon: (yogafan) Add support for Lenovo Yoga/Legion fan monitoring
This driver provides fan speed monitoring for Lenovo Yoga, Legion, and
IdeaPad laptops by interfacing with the Embedded Controller (EC) via ACPI.
To address low-resolution sampling in Lenovo EC firmware, a Rate-Limited
Lag (RLLag) filter is implemented. The filter ensures a consistent physical
curve regardless of userspace polling frequency.
Hardware identification is performed via DMI-based quirk tables, which
map specific ACPI object paths and register widths (8-bit vs 16-bit)
deterministically.
