hw/intc/aspeed: Support setting different memory size

Browse source 
According to the AST2700 datasheet, the INTC(CPU DIE) controller has 16KB
(0x4000) of register space, and the INTCIO (I/O DIE) controller has 1KB (0x400)
of register space.

Introduced a new class attribute "mem_size" to set different memory sizes for
the INTC models in AST2700.
