cmd_ide: enhance new feature "CONFIG_IDE_AHB"
Although most IDE controller is designed to be connected to PCI bridge, there are still some IDE controller support AHB interface for SoC design. The driver implementation of these IDE-AHB controllers differ from other IDE-PCI controller, some additional registers and commands access is required during CMD/DATA I/O. Hence a configuration "CONFIG_IDE_AHB" in cmd_ide.c is required to be defined to support these kinds of SoC controllers. Such as Faraday's FTIDE020 series and Global Unichip's UINF-0301.
