Subject: [PATCH 1/2] of: Add of_property_present() helper

Add an of_property_present() function similar to
fwnode_property_present(). of_property_read_bool() could be used
directly, but it is cleaner to not use it on non-boolean properties.

Signed-off-by: Rob Herring <robh@...nel.org>

I plan to add this for v6.3 and send most of the conversion patches in
the next cycle.
