[PATCH v1 02/15] aspeed/soc: support ADC for AST2700

[Jamin Lin]

Add ADC model for AST2700 ADC support.
The ADC controller registers base address is start at
0x14C0_0000 and its address space is 0x1000.
The ADC controller interrupt is connected to
GICINT130_INTC group at bit 16. The GIC IRQ is 130.
