dt-bindings: interrupt-controller: aspeed: Add AST2700 SCU IC compatibles

Browse Source 
Add compatible strings for the four SCU interrupt controller instances
on the AST2700 SoC (scu-ic0 to 3), following the multi-instance model used
on AST2600.

Also define interrupt indices in the binding header.
