Mark Brown e0838f6373 arm64/sme: Save and restore streaming mode over EFI runtime calls
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.
