hw/intc/aspeed: Add support for AST2700 SSP INTC

Browse source 
- Define new types for ast2700ssp INTC and INTCIO
- Add register definitions for SSP INTC and INTCIO
- Implement write handlers for SSP INTC and INTCIO
- Register new types in aspeed_intc_register_types

The design of the SSP INTC and INTCIO controllers is similar to
AST2700, with the following differences:

- 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-ssp
  Support SSPINT128 to SSPINT136 in INTC
  The INTCIO SSPINT_160_169 has 10 output pins, mapped as follows:
    Bit 0 -> SSPINT 160
    Bit 1 -> SSPINT 161
    Bit 2 -> SSPINT 162
    Bit 3 -> SSPINT 163
    Bit 4 -> SSPINT 164
