Some devicetrees specify gpio-line-names in the sgpio node despite it
not being defined by the binding. It's a reasonable thing to do, so
define the property to squash warnings such as:

    arch/arm/boot/dts/aspeed/aspeed-bmc-vegman-rx20.dtb: sgpio@1e780200: 'gpio-line-names' does not match any of the regexes: 'pinctrl-[0-9]+'
