According to the datasheet of ASPEED SOCs, a GPIO controller owns 4KB of register space for AST2700, AST2500, AST2400 and AST1030; owns 2KB of register space for AST2600 1.8v and owns 2KB of register space for AST2600 3.3v. It set the memory region size 2KB by default and it does not compatible register space for AST2700. Introduce a new class attribute to set the GPIO controller memory size for different ASPEED SOCs.
