[PATCH AUTOSEL 6.19-6.18] platform/x86: hp-wmi: Add Omen 16-xd0xxx fan and thermal support

[Sasha Levin]

From: Krishna Chomal <krishna.chomal108@xxxxxxxxx>

[ Upstream commit 3c99a545b372c77b5d39715968a141f523eccbf2 ]

The HP Omen 16-xd0xxx (board ID: 8BCD) has the same WMI interface as
other Victus S boards, but requires quirks for correctly switching
thermal profile (similar to HP Omen 16-wf1xxx, board ID: 8C78).

Add the DMI board name to victus_s_thermal_profile_boards[] table and
map it to omen_v1_thermal_params.

Testing on HP Omen 16-xd0xxx confirmed that platform profile is
registered successfully and fan RPMs are readable and controllable.

LLM Generated explanations, may be completely bogus:

## Analysis

This commit adds a DMI board name entry ("8BCD") for the HP Omen
16-xd0xxx laptop to the `victus_s_thermal_profile_boards[]` table,
mapping it to `omen_v1_thermal_params`. This is a hardware quirk/device
ID addition to an existing driver.

### Change Classification

This is a **hardware quirk addition** — one of the explicitly allowed
exception categories for stable backports. The change:
- Adds exactly 4 lines to an existing DMI matching table
- Uses an already-existing parameter set (`omen_v1_thermal_params`)
- Only affects the specific board ID "8BCD" (HP Omen 16-xd0xxx)
- Follows the exact same pattern as other entries in the table (e.g.,
  board "8C78" also uses `omen_v1_thermal_params`)

### Risk Assessment

**Extremely low risk:**
- The change is confined to a single DMI match table — it cannot affect
  any other hardware
- It uses existing infrastructure (`omen_v1_thermal_params`) that is
  already tested with board "8C78"
- The commit has both `Tested-by` and `Reviewed-by` tags from the
  subsystem maintainer (Ilpo Järvinen)
- No code logic changes, no new functions, no new data structures

### User Impact

Without this entry, HP Omen 16-xd0xxx users cannot:
- Control fan speeds through the platform profile interface
- Switch thermal profiles (performance/balanced/quiet)

This is real hardware enablement for real users — the "Tested-by" from a
different person than the author confirms at least two users need this.

### Stable Criteria Check

- **Obviously correct**: Yes — trivial table entry addition matching
  existing patterns
- **Fixes real issue**: Yes — enables hardware control on specific
  laptop (quirk category)
- **Small and contained**: Yes — 4 lines in one file
- **No new features/APIs**: Correct — uses existing driver
  infrastructure
- **Tested**: Yes — explicitly tested on the hardware

### Verification

- Verified the diff is purely a table entry addition to
  `victus_s_thermal_profile_boards[]` — no code logic changes
- Verified `omen_v1_thermal_params` is already used by board "8C78" in
  the same table, confirming it's an existing, tested parameter set
- Verified the commit has `Tested-by: Varad Amol Pisale` and `Reviewed-
  by: Ilpo Järvinen` (subsystem maintainer)
- Verified the change follows the exact DMI_MATCH pattern used by all
  other entries in the table
- The commit message explicitly states "Testing on HP Omen 16-xd0xxx
  confirmed that platform profile is registered successfully and fan
  RPMs are readable and controllable"

This is a textbook hardware quirk addition — small, safe, tested, and
enables real hardware for real users. It matches the stable exception
for device quirks/IDs perfectly.

**YES**
