Subject: [PATCH v1 1/2] dt-bindings: soc: samsung: usi: allow 64-bit address space

Some device trees, like the exynos2200 one, configure the root node
with #address-cells and #size-cells set to 2. However, the usi binding
expects 32 bit address space only. Allow these determining properties to
be set as 1 or 2 instead of a constant 1.
