[00/10] pinctrl: renesas: checker: Miscellaneous improvements

Hi Linus,

This patch series improves the Renesas pin control table validator
(enabled when DEBUG is defined, e.g. with CONFIG_DEBUG_PINCTRL=y), by:
  1. Suggesting which pin groups can share pins,
  2. Adding more checks to catch common errors.

If you enable the checker, you may be disappointed by the (lack of)
output.  Indeed, it is much easier to fix detected issues, than to get
the checker code in a state that is suitable for upstream submission
;-)
Hence most issues detected have been fixed already for quite some time,
or never arrived upstream in the first place. Recent fixes are [1] and
[2].

If accepted, I intend to queue this in renesas-pinctrl for v5.18.
Thanks for your comments!
