/**
  Passes capsules to the firmware with both virtual and physical mapping. Depending on the intended
  consumption, the firmware may process the capsule immediately. If the payload should persist
  across a system reset, the reset value returned from EFI_QueryCapsuleCapabilities must
  be passed into ResetSystem() and will cause the capsule to be processed by the firmware as
  part of the reset process.

                                location in physical memory of a set of capsules.

  @retval EFI_SUCCESS           Valid capsule was passed. If
                                CAPSULE_FLAGS_PERSIT_ACROSS_RESET is not set, the
                                capsule has been successfully processed by the firmware.
  @retval EFI_DEVICE_ERROR      The capsule update was started, but failed due to a device error.
