Subject: [PATCH] dt-bindings: iio: pressure: invensense,icp101xx: add binding

There is no txt file for it, add yaml for invensense,icp101xx family
which is already used in the driver.

Signed-off-by: Rodrigo Gobbi <rodrigo.gobbi.7@...il.com>

Very simple yaml for a i2c device with psu. The pin out for the rest of
the family (the other PNs) doesn`t change anything here, since the diff
were RESV pins (unused).

This yaml file falls in the same `category` as others that I`ve submitted, the
driver author, which might be still interested at this hardware, is no long contributing
(at least for what I`ve looked). Also, it`s email is still "at invensense", not "at tdk", either
way I`ll ping him here due the mention at the "maintainers" field:

Dear @Jean-Baptiste Maneyrol, I`ve noticed that since the driver was added,
there was no binding doc for it and this is what this patch is addressing.
In this case, a maintainer ref is required inside the .yaml file and I would
like to ask if I can add you in this case.
I would appreciate your comment or suggestion over this topic.

Tks all and regards.
