Subject: [PATCH v2] dt-bindings: iio: pressure: add invensense,icp10100

There is no txt file for it, add yaml for invensense,icp10100
which is already used in the driver.

@Krzysztof and @Jonathan,

from v1:
> Filename matching compatible, please.

and:
> No wild cards in file names please.  Just pick a device to name the binding
> after.  Wild cards have an annoying habit of getting messed up by companies
> releasing completely non compatible parts in the middle of what we thought
> was a reserved number range.
...understood the point about wildcards, I`ve changed that in this v2.
I was confused because when I was exploring other files over different trees, noticed
the same wildcard pattern like: [1] and [2] (maybe there are others).

[1] https://github.com/torvalds/linux/blob/master/Documentation/devicetree/bindings/power/supply/bq2515x.yaml#L81
[2] https://github.com/torvalds/linux/blob/master/Documentation/devicetree/bindings/i2c/i2c-mt65xx.yaml#L119

I`ve kept the "ICP-101xx" (wildcard) at title and description, if there is a problem with
that, let me know.

@Jean-Baptiste Maneyrol, tks for the answer and ack!
Best regards.

Changelog:
v2: removed wildcard + adding proper maintainer
v1: https://lore.kernel.org/all/20250626212742.7986-1-rodrigo.gobbi.7@gmail.com/
