dm: fdt: Add a function to decode phandles with arguments For GPIOs and other functions we want to look up a phandle and then decode a list of arguments for that phandle. Each phandle can have a different number of arguments, specified by a property in the target node. This is the "#gpio-cells" property for GPIOs. Add a function to provide this feature, taken modified from Linux 3.18. Signed-off-by: Simon Glass <sjg@chromium.org>
