When DEBUG is defined (e.g. if CONFIG_DEBUG_PINCTRL=y), the Renesas pin
control driver runs sanity checks against the pin control tables.  This
may cause lots of output on the console, and can be annoying in ARM
multi-platform kernels.  Fix this by only running the checks when
running on SuperH, or on a DT platform supported by the Renesas pin
controller driver.

To be queued in renesas-pinctrl-for-v5.12.
