[PATCH v6 3/6] dt-bindings: mfd: aspeed,ast2x00-scu: allow #size-cells range

[Ryan Chen]

The #size-cells property in the Aspeed SCU binding is currently
fixed to a constant value of 1. However, newer SoCs (ex. AST2700)
may require two size cells to describe certain subregions or
subdevices.

This patch updates the schema to allow #size-cells values in
the range of 1 to 2. This makes the binding more flexible
while maintaining compatibility with existing platforms.
It also resolves dt-binding validation warnings reported
by `make dt_binding_check`.
