fabric was re-architected: interrupt routing is programmable and
interrupt outputs can be directed to multiple upstream controllers
(PSP GIC, Secondary Service Processor (SSP) NVIC, Tertiary Service
Processor (TSP) NVIC, and Boot MCU interrupt controller). This design
requires route resolution and a controller hierarchy model which the
A0 binding cannot represent.

Remove the binding for the pre-production A0 design in favour of the
binding for the A2 production design. There is no significant user
impact from the removal as there are no existing devicetrees in any
of Linux, u-boot or Zephyr that make use of the A0 binding.

-title: Aspeed AST2700 Interrupt Controller
-
-description:
-  This interrupt controller hardware is second level interrupt controller that
-  is hooked to a parent interrupt controller. It's useful to combine multiple
-  interrupt sources into 1 interrupt to parent interrupt controller.

-      Depend to which INTC0 or INTC1 used.
-      INTC0 and INTC1 are two kinds of interrupt controller with enable and raw
-      status registers for use.
-      INTC0 is used to assert GIC if interrupt in INTC1 asserted.
-      INTC1 is used to assert INTC0 if interrupt of modules asserted.
