[PATCH v2 3/6] commands: of_property: use new of_read_file

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

Recent addition of of_read_file also involved switching over nearly all
open coded instances to use it. of_property seems the only remaining
instance where of_read_file can be used, but isn't. Switch it over.
