This is possible because both 32B and 64B variants have
the same function prototype.


However, I am not keen on doing so for ecc_handle(),
so, at this moment, I am not keen on doing so only for setup_dma() either.

If I see more cases that fit in callback handler approach,
I will think about switching to it with consistency.
