Jianqun Xu 9df5bfa9fc pinctrl: rockchip: treat pcfg_xxx nodes as invalid function nodes
Look at the pinmux-functions debug node, there are several pcfg_xxx
nodes which actually are not pinctrl functions:

Under RV1126 EVB:
  function: pcfg-pull-up, groups = [ ]
  function: pcfg-pull-down, groups = [ ]
  function: pcfg-pull-none, groups = [ ]
  function: pcfg-pull-none-drv-level-1, groups = [ ]
  function: pcfg-pull-none-drv-level-2, groups = [ ]
  function: pcfg-pull-none-drv-level-3, groups = [ ]
  function: pcfg-pull-up-drv-level-1, groups = [ ]
  function: pcfg-pull-up-drv-level-2, groups = [ ]
  function: pcfg-pull-none-smt, groups = [ ]
  function: pcfg-output-low-pull-down, groups = [ ]
  function: acodec, groups = [ acodec-pins ]

This patch fixs the function node valid check to ignore them.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
