[PATCH v6 0/1] Update correct AST2700 interrupt controller binding

[Ryan Chen]

Update the AST2700 interrupt controller binding to match the actual
hardware and the irq-aspeed-intc driver behavior.

v6:
- aspeed,ast2700-intc.yaml
 update interrupt-cells, interrupts.

v5:
- Adds two new YAML bindings:
 - aspeed,ast2700-intc0.yaml
 - aspeed,ast2700-intc1.yaml
- irq-aspeed-intc.c
 - add aspeed,ast2700-intc0-ic, aspeed,ast2700-intc0-ic compatible.

v4:
- aspeed,ast2700-intc.yaml
 - Clarify the relationship between INTC0/INTC1 parent nodes, the
   aspeed,ast2700-intc-ic child nodes, and the GIC.
 - Add a block diagram and DT examples showing the cascaded wiring
   (GIC <- INTC0 <- INTC1 children).
 - Mirrors the datasheet-described topology and register map, including
   the separation of INTC0/INTC1 regions.
 - Lets DT unambiguously express first-level (GIC parent) and cascaded
   second-level (INTC0 parent) interrupt controllers via examples that
   use `interrupts` for INTC0 children and `interrupts-extended` for
   INTC1 children routed into INTC0.

- irq-ast2700-intc.c
 - Drop all string decoding and human readable tables.
   Debugfs now dumps raw routing/protection registers only.
 - Split into a separate source file and made it modular
 - If the compatible not match ast2700-intc0/1, bail out return -ENODEV.

v3:
- aspeed,ast2700-intc.yaml
  - Clarify the relationship between INTC0/INTC1 parent nodes, the
    aspeed,ast2700-intc-ic child nodes, and the GIC.
  - Add a block diagram and DT examples showing the cascaded wiring
    (GIC <- INTC0 <- INTC1 children).
  - Mirrors the datasheet-described topology and register map, including
    the separation of INTC0/INTC1 regions and their routing/protection
    registers.
  - Lets DT unambiguously express first-level (GIC parent) and cascaded
    second-level (INTC0 parent) interrupt controllers via examples that
    use `interrupts` for INTC0 children and `interrupts-extended` for
    INTC1 children routed into INTC0.
  
- irq-aspeed-intc.c
  - separate c file from irq-aspeed-intc.c
  - make m

v2:
- fix dt bindingcheck
