[PATCH 1/7] dt-bindings: pinctrl: Add support for Broadcom STB pin controller

["Ivan T. Ivanov" <iivanov@xxxxxxx>]

It looks like they are few revisions of this chip which varies
by number of pins. Perhaps not all of them are available on the
market. Perhaps some of them where early engineering samples,
I don't know. I decided to keep all of them just in case.
