The INTC controller supports GICINT128 to GICINT136, mapping 1:1 to input and output IRQs 0 to 8. Previously, the formula "address & 0x0f00" was used to derive the IRQ index numbers. However, the INTC controller also supports GICINT192_201, mapping 1 input IRQ pin to 10 output IRQ pins. The pin numbers for input and output are different. It is difficult to use a formula to determine the index number of INTC model supported input and output IRQs. To simplify and improve readability, introduces the AspeedINTCIRQ structure to save the input/output IRQ index and its enable/status register address. Introduce the "aspeed_2700_intc_irqs" table to store IRQ information for INTC. Introduce the "aspeed_intc_get_irq" function to retrieve the input/output IRQ pin index from the provided status/enable register address.
