[PATCH v2 0/4] hwmon: Add ASUS ROG Ryujin III support

Add hardware monitoring support for ASUS ROG Ryujin III coolers.

Compared with the Ryujin II, the Ryujin III uses different offsets in
its status reports and a different cooler-duty channel. It also does not
expose the Ryujin II's external fan-controller channels. The first patch
moves those details into per-device configuration, and the second adds
the Extreme and EVA Edition variants. The third patch, authored by Will
Smith, adds the White Edition USB ID. Will confirmed his authorship
sign-off and tested that variant on his hardware.

The fourth patch rejects HID devices without per-device configuration
before that configuration is dereferenced. This prevents dynamic new_id
bindings from causing a NULL pointer dereference.

The Ryujin III implementation and White Edition were tested through the
linked project pull requests. The EVA Edition hardware was tested by me.

Codex using gpt-5.6-sol assisted with porting the changes to the current
hwmon tree, organizing the patch series, updating documentation and
commit messages, and running build, checkpatch, Sparse, and Sphinx
validation. I reviewed and tested the resulting changes on ROG Ryujin
III EVA Edition hardware.

The v2 series passes git diff --check and checkpatch --strict. The driver
object compiles in-tree with W=1 in both built-in and module
configurations, and Sparse reports no findings for either configuration.
The range-diff confirms that the first three patches are unchanged from
v1.

Changes in v2:
- Add a final patch validating per-device configuration, as requested by
  Guenter Roeck.
- Rebase the series onto the current hwmon-next branch.
