On mt8192, the pinctrl node has pinctrl groups to group pin
configurations. Each pinctrl group contains one or more pinmux subnodes
to list needed pins and their configurations. By supporting multiple
subnodes, we can configure different pin characteristics
(driving/pull-up/pull-down/etc.) in a pinctrl group.
Update the mt8192 pinctrl dt-binding to add the missing pinctrl group
node that wraps the pinmux subnodes and update the example at the end.
While at it, also remove the example embedded in the description since
it is redundant to the already supplied example at the end.
This same change was done for mt8195 in commit 79dcd4e840 ("dt-bindings:
pinctrl: mt8195: add wrapping node of pin configurations").

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
