Subject: [PATCH] devfreq: imx-bus: Use of_property_present()

Use of_property_present() to test for property presence rather than
of_get_property(). This is part of a larger effort to remove callers of
of_get_property() and similar functions. of_get_property() leaks the DT
property data pointer which is a problem for dynamically allocated
nodes which may be freed.
