[PATCH 4/4] dt-bindings: interrupt-controller: aspeed: Remove legacy AST2700 interrupt binding

[Ryan Chen]

Remove the legacy AST2700 interrupt controller Devicetree binding.

The legacy binding was limited to a PSP-centric view of the interrupt
architecture and cannot describe interrupt routing and protection for
the full AST2700 system.

It is superseded by the new ASPEED AST2700 INTC0/INTC1 binding, which
describes the interrupt controllers at the block-function level.

There are no known upstream users of the removed 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.
