gpio: Add Aspeed GPIO driver
The Aspeed GPIO driver supports the GPIO controllers found in the
AST2400, AST2500 and AST2600 BMC SoCs. The implementation is a cut-down
copy of the upstream Linux kernel driver, adapted for u-boot.

+ Say yes here to support the Aspeed GPIO driver. The controller
+ is found in the AST2400, AST2500 and AST2600 BMC SoCs and
+ provides access to over 200 GPIOs on each chip.
