hwmon: (yogafan) Add support for new Lenovo models
Add DMI quirk entries and map correct ACPI paths and configurations for
additional Lenovo laptop models including the LOQ 15IAX9,
XiaoXin Pro 13ARE 2020, IdeaPad 3 15ALC6, Legion Pro 7 16AFR10H,
Yoga Pro 7 14IAH10, and Yoga 7 16ARP8.
Reorder the DMI quirk table to evaluate specific model matches before
generic family fallbacks, preventing DMI shadowing.
