[PATCH] ARM: dts: picoxcell: drop unused reg-io-width from DW APB GPIO controller

[Krzysztof Kozlowski]

The Synopsys DesignWare APB GPIO controller driver does not parse
reg-io-width and dtschema does not allow it so drop it to fix dtschema
warnings like:

  arch/arm/boot/dts/picoxcell-pc7302-pc3x2.dt.yaml: gpio at 20000:
    'reg-io-width' does not match any of the regexes: '^gpio-(port|controller)@[0-9a-f]+$', 'pinctrl-[0-9]+'
