Subject: [PATCH 2/3] lib/vsprintf: Move integer format types to the top

From: Geert Uytterhoeven <geert+renesas@...der.be>

Move the format types for 64-bit integers and configurable size integers
to the top, so they're next to the other integer format types.
While at it, add the missing format types for s32 and u32.
