[PATCH V2] platform/x86: hp-wmi: fix platform profile values for Victus 15-fb0xxx (8A3D)

[Sourav Nayak <nonameblank007@gmail.com>]

Currently Victus 15-fb0xxx (8A3D) takes victus_s_thermal_params,
which causes it to register as incorrect EC layout while cold boot.

- On other hand windows Omen Gaming Hub registers EC offset as 0x95,
- which is set in driver as HP_OMEN_EC_THERMAL_PROFILE_OFFSET.
- So, address it by adding victus_s_ec_thermal_params.

- Also perfcontrol modes as performance (0x1), default (0x0), quiet
(0x3) registers. So, add support for quiet mode.

Also, hp_wmi_fan_speed_max_reset() caused fans to freeze during loads at
0RPM, introduce a 'if' statement to resolve it by calling hp_wmi_fan_speed_max_set(0),
and passing platform active again to reactive curves. Test data:

auto/max:
hp-isa-0000
Adapter: ISA adapter
fan1:        5400 RPM
fan2:        5200 RPM

mannual[255]:
hp-isa-0000
Adapter: ISA adapter
fan1:        5800 RPM
fan2:        5800 RPM
