bprintf() is unused. Remove it. It was added in the commit 4370aa4aa753
("vsprintf: add binary printf") but as far as I can see was never used,
unlike the other two functions in that patch.

Looks good to me:

Acked-by: Petr Mladek <pmladek@suse.com>

I assume that Sven is going to take it via the ftrace tree as he
suggested at https://lore.kernel.org/r/20241002104807.42b4b64e@gandalf.local.home

Yeah, since I'm basically the only user of it, it's best it goes through my
testing.
