With the introduction of the RK3576, the maximum device function ID used
increased to 14, as anyone can easily verify for themselves with:

  rg -g '*-pinctrl.dtsi' '<\d+\s+RK_P..\s+(?<func>\d+)\s.*>;$' --trim \
  -NI -r '$func' arch/arm64/boot/dts/rockchip/ | sort -g | uniq

Unfortunately, this wasn't caught by dt-validate as those pins are
omit-if-no-ref and we had no reference to them in any tree so far.

Once again kick the can down the road by increasing the limit to 14.

Is this something I can just apply?
