  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.

I did provide an RB for this patch on the same day you sent it,
thinking it was part of a larger refactoring effort.  But taking
another look now I see that it is not the case and will apply it right
away.
