I believe these should all be the same between Norrin (Nyan), Big, and
Blaze, so I'd go with whatever is in the Norrin pinmux config (which I
believe is what Simon's patch is based on).

These are the differences you've collected between blaze and big from
the schematic or... ?

usb_vbus_en2 is not connected on all Nyan-based boards, so I would
just use whatever the Norrin config uses.

I would expect these to be like Venice2/Norrin: input enabled,
open-drain, no pull.
