Is this used for anything besides getting the regmap? Can you get the
pointer to the parent in probe and use that to get the regmap pointer
from dev_get_remap() and also use the of_node of the parent to register

dev_get_regmap() is pretty expensive, I'd not advise using it in
anything that might approximate a fast path.  It's kind of debatable
when I2C gets involved but still feels wrong.

I'm suggesting the regmap is acquired in probe and a pointer is stored
here in this structure. That is not a fastpath as far as I know.

Ah, great - that's the intended usage.
