[PATCH v3 05/10] hw/arm/aspeed_ast1040: Reuse AST2700 GPIO controller model

[Jamin Lin <jamin_lin@aspeedtech.com>]

The AST1040 GPIO controller is compatible with the AST2700 GPIO
controller implementation.

Reuse the existing "aspeed.gpio-ast2700" device model for AST1040
instead of introducing a separate implementation.

Add the GPIO device initialization, MMIO mapping, and IRQ wiring
for the AST1040 SoC model.
