1) PcdFlashNvStorageFtwWorkingSize, PcdFlashNvStorageFtwWorkingBase, PcdFlashNvStorageFtwSpareSize, PcdFlashNvStorageFtwSpareBase, PcdFlashNvStorageVariableSize PcdFlashNvStorageVariableBase should in gEfiMdeModulePkgTokenSpaceGuid.

2) Use FlashMapHob to get the address and length of FV instead of using PCD. 
3) Use hard code environment in WinNtBusDriver but not dynamic PCD.
