misc: rp1: do not put borrowed OF node

Browse source

dev_of_node() returns the device's OF node without taking a new
reference. rp1_probe() stores that borrowed pointer in rp1_node, but
drops it with of_node_put() on both success and failure paths.

Dropping a reference that was never acquired can underflow the node's
refcount and leave later users with a stale OF node. Remove the
of_node_put() calls and keep rp1_node as a borrowed pointer.
