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`.

I said no last time and now when we see the DTS it is visible it makes
no sense. Please reply in the DTS patch in the EXACT place where this is
being used.

NAK
