[PULL 37/46] hw/arm/aspeed_ast27x0: Define an Array of AspeedINTCState with Two Instances

["Cédric Le Goater" <clg@redhat.com>]

From: Jamin Lin <jamin_lin@aspeedtech.com>

Updated Aspeed27x0SoCState to include an intc[2] array instead of a single
AspeedINTCState instance. Modified aspeed_soc_ast2700_get_irq and
aspeed_soc_ast2700_get_irq_index to correctly reference the corresponding
interrupt controller instance and OR gate index.

Currently, only GIC 192 to 201 are supported, and their source interrupts are
from INTCIO and connected to INTC at input pin 0 and output pins 0 to 9 for
GIC 192-201.

To support both AST2700 A1 and A0, INTC input pins 1 to 9 and output pins
10 to 18 remain to support GIC 128-136, which source interrupts from INTC.
