Thanks, think we can simplify a bit and remove the warning ?

I think we can remove this now no?

Hmm I think we need to keep it to inform users about that

What does this PR do?
Replaces #26560
Fixes #26451
Proposes a simpler fix for dealing with FA-2 + PEFT + quantization fine-tuning where users usually cast all other modules (e.g. LayerNorms) in fp32 for training stability.
With #26761 being introduced, it is now much simpler to retrieve model's original dtype, note also that

Added also a nice test
