When saving and restoring the floating point state over an EFI runtime call ensure that we handle streaming mode, only handling FFR if we are not in streaming mode and ensuring that we are in normal mode over the call into runtime services.

We currently assume that ZA will not be modified by runtime services, the specification is not yet finalised so this may need updating if that changes.
