remoteproc: Use of_property_present()

Use of_property_present() to test for property presence rather than
of_(find|get)_property(). This is part of a larger effort to remove
callers of of_find_property() and similar functions. of_find_property()
leaks the DT struct property and data pointers which is a problem for
dynamically allocated nodes which may be freed.
