Subject: [PATCH v2] dt-bindings: iio: gyroscope: invensense,itg3200: add binding

There is no txt file for it, add yaml for invensense,itg3200 gyroscope.

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

Originally I`ve added @Jonathan as the binding maintainer due another thread
but @Krzysztof mentioned at v1: "...this should be someone interested in the hardware".
I`m not sure who might be this person in this case, a reasonable choice would be
the original author of the driver, but looks like his last patch is from a
long time ago [2] but I`ll ping here.

Dear @Manuel Stahl, 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.

Changelog:
v2: 
    - removed the register map link; there is no datasheet available at public ref. At [1],
    it is just a product overview, so we can`t use it;
    - add supplies and external clocks (I`ve used as ref iio/gyroscope/invensense,mpu3050.yaml);
    - add the author of the driver as the maintainer of this file but I`m CC him in
    order to get his opinion about it;
    - adding some CC missing at v1;
