[PATCH] platform/x86: hp-wmi: Add fan control support for OMEN 8C4D

[PATCH] platform/x86: hp-wmi: Add fan control support for OMEN 8C4D

[Lauri Sarap]

The HP OMEN Transcend 16-u1xxx with board ID 8C4D uses the
Victus S fan control path with OMEN v1 thermal profile parameters.

Manual fan control has been tested through the hwmon pwm interface. The
legacy OMEN profile path exposes controls but does not change fan speed
on this board; the Victus S table with omen_v1_thermal_params provides
working fan RPM changes.

Thanks for the patch.

hp-wmi driver's .driver_data scope has been expanded. Please check the 
very changes recently added into the review-ilpo-next branch in the 
platform drivers repo and adapt this patch accordingly. Then post v2, 
thank you.
