hwmon: (yogafan) Add support for Lenovo LOQ 15IAX9

Browse source

Add the Lenovo LOQ 15IAX9 product family to the yogafan dmi_system_id
table. Unlike the Legion series, ACPI table extraction reveals this LOQ
utilizes an 8-bit EC architecture with a 100x multiplier, but maintains
a dual-fan setup via the \_SB.PC00.LPCB.EC0.FA1S and FA2S paths.

A new loq_15iax9_8bit_dual_cfg structure was added to properly map these
hardware registers and calculate RPMs correctly while avoiding path
conflicts with AMD-based LOQ variants.
