/**
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 FvFormat 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 If the firmware volume originally came from a firmware file, then these point to the
parent firmware volume name. If it did not originally come from a firmware file,
these should be NULL.
@param ParentFileName If the firmware volume originally came from a firmware file, then these point to the
firmware volume file. If it did not originally come from a firmware file,
these should be NULL.
