a. Add check validation of RemainingDevicePath in Supported()
b. In Star() function, if RemaingDevicePath is the End of Device Path Node, don't create child device and return EFI_SUCCESS.
2. fixed one device path issue in ScsiBus driver.

The others changes include:
1. Check RemainingDevicePath at beginning of Supported(), make sure it has been verified before Start() is called.
2. Check IO protocol firstly rather than EfiDevicePathProtocolGuid, reduce the times entering into Start() function because EfiDevicePathProtocolGuid existed on most of handle.
3. If no any child device is created on last time, and RemainingDevicePath is valid Uart Devcie path, go on creating child device handle based on this RemainingDevicePath.

Our UEFI Driver supports both SCSI Passthru (SPT) and Ext SCSI Passthru (That is our driver installs both SCSI Passthru and Ext SCSI Passthru). When we unload our driver SCSI Bus driver closes only ESPT and keeps SPT open. Due to this when I load my driver second time the SPT installation will fail and now attempting to unload will either crash the system or hang the system.

2. Get the command/control register base address for each channel through IDE common registers.
3. Correctify some return status to sync with newest Uefi Spec 2.1
