[PATCH v2 0/4] irqchip: Add Aspeed SCU Interrupt Controller

The Aspeed SOCs provide some interrupts through the System Control
Unit registers. Add an interrupt controller that provides these
interrupts to the system. Add the interrupt controller to the AST25XX
and AST26XX devicetrees.

Changes since v1:
 - add a spinlock to protect read-modify-write operation for irq masking
 - use readl/writel relaxed versions
 - add a comment explaining the irq status/enable register
 - provide affinity callback that returns -EINVAL
