Jamin Lin b008465d65 hw/intc/aspeed: Support setting different register size
Currently, the size of the regs array is 0x2000, which is too large. So far,
it only use GICINT128 - GICINT134, and the offsets from 0 to 0x1000 are unused.
To save code size, introduce a new class attribute "reg_size" to set the
different register sizes for the INTC models in AST2700 and add a regs
sub-region in the memory container.
