revert the change on BdsConsole. when doing minimal boot, the ConsoleIn variable is used to store existing input device's device path. If the device can not be connected, its device path will be removed from ConsoleIn.

So due the usb hot plug feature, we should always connect USB host controller according to the consolein device provided by PlatformData file before entering frontpage. This way can avoid usb device can not work in frontpage phase.
