Subject: [PATCH] firmware: Use of_property_present() for testing DT property presence

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 am assuming you will route this as it has other changes as well in the
patch.

I can also pick this up along with the Tegra changes if Rob doesn't
want to take it. But also feel free to take this through whatever tree
works best, for the Tegra parts:
