[edk2-devel] [PATCH 2/3] MinPlatformPkg: Update the comments of GetInformation function

["Qingyu" <qingyu.shang@intel.com>]

Refer to Uefi spec 2.10 section 11.11.2, add a new retval
EFI_NOT_FOUND to EFI_ADAPTER_INFORMATION_PROTOCOL.GetInformation().
Reference: [mantis #1866] - GetInfo() of Adapter Information
Protocol should have a provision for IHV to return no data.
