[PATCH] dt-bindings: arm: bcm: bcm4908: fix yaml validation

[Rafał Miłecki]

From: Rafał Miłecki <rafal at milecki.pl>

Root node can obviously have various subnodes so "additionalProperties"
should be set to true.

This fixes:
arch/arm64/boot/dts/broadcom/bcm4908/bcm4908-asus-gt-ac5300.dt.yaml: /: '#address-cells', '#size-cells', 'aliases', 'axi at 81000000', 'chosen', 'clocks', 'cpus', 'gpio-keys-polled', 'interrupt-parent', 'memory at 0', 'model', 'pmu', 'soc', 'timer', 'ubus at ff800000' do not match any of the regexes: 'pinctrl-[0-9]+'
        From schema: Documentation/devicetree/bindings/arm/bcm/brcm,bcm4908.yaml

Sorry Florian for that. I've just learnt dtbs_check.
