[PATCH] soc: sunxi: Use of_property_present() for testing DT property presence

[Jernej Škrabec]

> 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.
