Added support for multiple output pins in the INTC controller to
accommodate the AST2700 A1.

Introduced "num_outpins" to represent the number of output pins. Updated the
IRQ handling logic to initialize and connect output pins separately from input
pins. Modified the "aspeed_soc_ast2700_realize" function to connect source
orgates to INTC and INTC to GIC128 - GIC136. Updated the "aspeed_intc_realize"
function to initialize output pins.
