[PATCH] dt-bindings: pinctrl: st,stm32: Document gpio-line-names

[Marek Vasut <marex@xxxxxxx>]

Document gpio-line-names property as valid property.
This fixes dtbs_check warnings when building current Linux DTs:

"
arch/arm/boot/dts/stm32mp153c-dhcom-drc02.dtb: pinctrl@50002000: gpio@50009000: 'gpio-line-names' does not match any of the regexes: 'pinctrl-[0-9]+'
"
