Each GPIO pin has their own individual control register and users are able to set one GPIO pin’s direction, interrupt enable, input mask and so on in the same one control register. AST2700 does not have GPIO18_XXX registers for GPIO 1.8v, removes ASPEED_DEV_GPIO_1_8V. It is enough to only have ASPEED_DEV_GPIO device in AST2700. Add GPIO model for AST2700 GPIO support. The GPIO controller registers base address is start at 0x14C0_B000 and its address space is 0x1000. The AST2700 GPIO controller interrupt is connected to GICINT130_INTC at bit 18. Therefore, correct GPIO irq 130.
