[ Upstream commit 246167b17c14e8a5142368ac6457e81622055e0a ]

Boards Pro WS WRX90E-SAGE SE has got a nct6775 chip, but by default there's
no use of it because of resource conflict with WMI method.

Add the board to the WMI monitoring list.

LLM Generated explanations, may be completely bogus:

## Analysis

### Commit Message Analysis
This commit adds a board identifier string ("Pro WS WRX90E-SAGE SE") to
the `asus_msi_boards[]` list in the nct6775 hwmon driver. The commit
message explains that this ASUS motherboard has an nct6775 hardware
monitoring chip, but it cannot be used by default due to a resource
conflict with WMI methods. Adding the board to the WMI monitoring list
resolves this conflict and enables hardware monitoring.

### Code Change Analysis
The change is a **single line addition** — inserting one string into an
alphabetically sorted list of board names:

```c
"Pro WS WRX90E-SAGE SE",
```

This is inserted between "Pro WS W790E-SAGE SE" and "ProArt
B650-CREATOR", maintaining alphabetical order. No logic changes, no new
functions, no structural modifications.

### Classification: Hardware Quirk / Device ID Addition
This falls squarely into the **"hardware quirks/workarounds"** exception
category for stable backports. The `asus_msi_boards[]` list is
effectively a board-level quirk table that tells the driver to use WMI-
based monitoring instead of direct I/O, resolving the resource conflict.
Without this entry, users of this specific motherboard cannot use
hardware monitoring at all.

### Stability Indicators
- **Tested-by:** Marcus confirmed the fix works on the actual hardware
- **Bug report link:**
https://bugzilla.kernel.org/show_bug.cgi?id=204807 — this is a
documented real-world issue
- **Reviewed and merged by:** Guenter Roeck, the hwmon subsystem
maintainer
- **Pattern:** Identical to dozens of other board additions in this same
file that have been backported to stable

### Risk Assessment
- **Risk: Extremely low.** Adding a string to a board match list cannot
affect any other board or any other code path. The match is exact —
only the "Pro WS WRX90E-SAGE SE" board is affected.
- **Scope:** Single line in a single file
- **Dependencies:** None — the WMI monitoring infrastructure already
exists in stable trees
- **Regression potential:** Essentially zero

### User Impact
Without this fix, users of the ASUS Pro WS WRX90E-SAGE SE motherboard (a
workstation-class board) have no hardware monitoring capability. This is
a real user-reported bug (kernel bugzilla #204807) with a tested fix.

### Stable Criteria Check
1. **Obviously correct and tested:** Yes — single string addition,
tested by user
2. **Fixes a real bug:** Yes — hardware monitoring doesn't work without
it
3. **Important issue:** Yes — complete loss of hwmon functionality for
this board
4. **Small and contained:** Yes — one line
5. **No new features:** Correct — enables existing functionality on
specific hardware
6. **Applies cleanly:** Very likely — it's a simple list insertion

**YES**
