Add checks for legacy function GPIO descriptors: 1. Function GPIOs must have a name, 2. Names must be unique, 3. Enum ID values must be unique. This exposes bugs like those fixed in - commit884caadad1("pinctrl: sh-pfc: sh7734: Fix duplicate TCLK1_B"), - commit55b1cb1f03("pinctrl: sh-pfc: sh7264: Fix CAN function GPIOs"), - commit02aeb2f215("pinctrl: sh-pfc: sh7269: Fix CAN function GPIOs"), - commitdb9c07272c("sh: sh7264: Remove bogus SSU GPIO function definitions"), - commitb4fba344a2("sh: sh7269: Remove bogus SSU GPIO function definitions").

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.
