hw/intc/aspeed: Add Support for Multi-Output IRQ Handling
This update introduces support for handling multi-output IRQs in the AST2700
interrupt controller (INTC), specifically for GICINT192_201. GICINT192_201 maps
1:10 to input IRQ 0 and output IRQs 0 to 9. Each status bit corresponds to a
specific IRQ.
Implemented "aspeed_intc_set_irq_handler_multi_outpins" to handle IRQs with
multiple output pins. Introduced "aspeed_intc_status_handler_multi_outpins"
for managing status registers associated with multi-output IRQs.
Added new IRQ definitions for GICINT192_201 in INTC.
Adjusted the IRQ array to accommodate 10 input pins and 19 output pins,
aligning with the new GICINT192_201 mappings.
