At present we support reading a string list a string at a time. Apart from being inefficient, this makes it impossible to separate reading of the devicetree into the of_to_plat() method where it belongs, since any code which needs access to the string must read it from the devicetree. Add a function which returns the string property as an array of pointers to the strings, which is easily used by clients. Signed-off-by: Simon Glass <sjg@chromium.org>
