In INTC, each interrupt of INT 128 to INT136 combines 32 interrupts. Introduce a new aspeed_intc class with instance_init and realize handlers. QEMU supports ARM Generic Interrupt Controller, version 3(GICv3) but not support Shared Peripheral Interrupt (SPI), yet. This patch added work around to set GICINT132[18] which was BMC UART interr= upt if it received GICINT132, so users are able to type any key from keyboard to trigger GICINT132 interrupt until AST2700 boot into login prompt. It is a temporary solution.
