cpufreq: Use of_property_present() for testing DT property presence

Browse Source 
[ Upstream commit b8f3a396a7 ]

It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.
