hw/arm/aspeed_ast27x0-tsp: Introduce AST27x0 A1 TSP SoC

AST2700 TSP(Tertiary Service Processor) is a Cortex-M4 coprocessor
The patch adds support for TSP with following update:

- Introduce Aspeed27x0TSPSoCState structure in aspeed_soc.h
- Implement initialization and realization functions
- Add support for UART, INTC, and SCU devices
- Map unimplemented devices for IPC and SCUIO
- Defined memory map and IRQ maps for AST27x0 A1 TSP SoC

The IRQ mapping is similar to AST2700 CA35 SoC, featuring a two-level
interrupt controller.

Difference from AST2700:

    - AST2700
      - Support GICINT128 to GICINT136 in INTC
      - The INTCIO GIC_192_201 has 10 output pins, mapped as follows:
          Bit 0 -> GIC 192
          Bit 1 -> GIC 193
          Bit 2 -> GIC 194
          Bit 3 -> GIC 195
          Bit 4 -> GIC 196

    - AST2700-tsp
      - Support TSPINT128 to TSPINT136 in INTC
      - The INTCIO TSPINT_160_169 has 10 output pins, mapped as follows:
          Bit 0 -> TSPINT 160
          Bit 1 -> TSPINT 161
          Bit 2 -> TSPINT 162
          Bit 3 -> TSPINT 163
          Bit 4 -> TSPINT 164
