Thanks for your comments.

This is a minor reset control only for XCVR devices, two reset bits
are accessed.

If we move to an auxiliary device,  we need to define a new header file
and a new driver, which will bring more code size and complexity.

So is it necessary to separate it to another auxiliary driver/device?

And add Philipp Zabel in loop for review.
