ARM: dts: marvell: orion: drop incorrect address/size-cells in GPIO keys

Bindings do not allow address/size-cells in GPIO keys and the GPIO keys
is not a bus, see dtbs_check warnings:

  orion5x-lacie-ethernet-disk-mini-v2.dtb: gpio-keys: '#address-cells', '#size-cells' do not match any of the regexes: '^(button|event|key|switch|...
