These calls are only made redundant by this patch.

Only since you removed the pm_runtime_put() in
rzv2h_usb2phy_reset_probe(). It feels like the important part of this
patch is actually the side note:

So this is a reliability fix first and foremost?
The IP must be active to reliably keep reset lines at the configured
level?

If so, please make this clear in the commit subject and description.
