Routine Description:
Entry point for the driver.
This routine gets info from the PlatformInfoHob and produces a protocol

Arguments:
ImageHandle - Image Handle.
SystemTable - EFI System Table.
Returns:
EFI_SUCCESS - Function has completed successfully.
Others - All other error conditions encountered result in an ASSERT.
