/**
    Install a EFI_PEI_FIRMWARE_VOLUME_INFO PPI to inform PEI core about the existence of a new Firmware Volume.
  
    The function allocate the EFI_PEI_PPI_DESCRIPTOR structure and update the fields accordingly to parameter passed
    in and install the PPI.
    
    @param  FvStart              Unique identifier of the format of the memory-mapped firmware volume. If NULL is specified,
                                         EFI_FIRMWARE_FILE_SYSTEM2_GUID is used as the Format GUID.
    @param  FvInfo               Points to a buffer which allows the EFI_PEI_FIRMWARE_VOLUME_PPI to
                                         process the volume. The format of this buffer is specific to the FvFormat. For
                                         memory-mapped firmware volumes, this typically points to the first byte of the
                                         firmware volume.
    @param  FvInfoSize          Size of the data provided by FvInfo. For memory-mapped firmware volumes, this is
                                         typically the size of the firmware volume.
    @param  ParentFvName, ParentFileName      If the firmware volume originally came from a firmware file, then these point to the
                                          parent firmware volume name and firmware volume file. If it did not originally come
                                          from a firmware file, these should be NULL
