I don't have a specific wording in the style you like right now, and
like I say I'm not sure it's too important since the actual chagne looks
good.  The main thing is just that the original thought was that we'd
not supply any register data unless in streaming mode which does due to
the use of one bit boil down to setting the FPSIMD value for the flag,
but the intent was more that the data format flag was rendered
irrelevant by the lack of data.  I was definitely aware that the two
flags were just a single bit - I distinctly remember seeing that and
thinking how unhelpful it was.  

Life would be a lot simpler and we probably wouldn't loose much if we
didn't support the FPSIMD format in the SVE regset but that ship is far
over the horizon.

Yeah, might take a little bit since some other stuff blew up and my CI's
a bit miserable right now.
