[PATCH] dt-bindings: pinctrl: st,stm32: Document interrupt-controller property

[Marek Vasut <marex@xxxxxxx>]

Document interrupt-controller property and its interrupt-cells.
This fixes dtbs_check warnings when building current Linux DTs:

"
arch/arm/boot/dts/stm32mp153c-dhcom-drc02.dtb: pinctrl@50002000: gpio@5000a000: '#interrupt-cells', 'interrupt-controller' do not match any of the regexes: 'pinctrl-[0-9]+'
"
