irqchip/ast2700-intc: Add AST2700-A2 support
The AST2700 interrupt fabric is shared by multiple integrated processors
(PSP/SSP/TSP/BootMCU), each with its own interrupt controller and its own
devicetree view of the system. As a result, interrupt routing cannot be
treated as fixed: the valid route for a peripheral interrupt depends on
which processor is consuming it.
The INTC0 driver models this by creating a hierarchical irqdomain under
the upstream interrupt controller selected by the interrupt-parent
property in the devicetree. Information derived from this relationship
is incorporated into the route resolution logic for the controller.
The INTC1 driver implements the banked INTM-fed controller and forwards
interrupts toward INTC0, without embedding assumptions about the final
destination processor.
