This patch series adds support for the SCU (System Control Unit) interrupt
controllers found in the Aspeed AST2700 SoC.

The AST2700 integrates multiple SCU interrupt groups, architecturally
similar to those in the AST2600, but using split registers for interrupt
enable (IER) and interrupt status (ISR), whereas AST2600 uses combined
registers.
