[PATCH] reset: eyeq: drop device_set_of_node_from_dev() done by parent

Our parent driver (clk-eyeq) now does the
device_set_of_node_from_dev(dev, dev->parent)
call through the newly introduced devm_auxiliary_device_create() helper.

Doing it again in the reset-eyeq probe would be redundant.
Drop both the WARN_ON() and the device_set_of_node_from_dev() call.
Also fix the following comment that talks about "our newfound OF node".
