dt-bindings: vexpress-sysreg: Allow for no child nodes

Browse Source 
It is valid for arm,vexpress-sysreg to have no child nodes when either
the deprecated binding without child nodes is used or a platform
has no GPIOs. If there are no child nodes, then "#address-cells" and
"#size-cells" should not be required. However, "reg" should be present
in all cases, so let's add it now.
