    dt: add property iteration helpers

    This patch adds macros of_property_for_each_u32() and
    of_property_for_each_string(), which iterate over an array of values
    within a device-tree property. Usage is for example:

    struct property *prop;
    const __be32 *p;
    u32 u;
    of_property_for_each_u32(np, "propname", prop, p, u)
        printk("U32 value: %x\n", u);

    struct property *prop;
    const char *s;
    of_property_for_each_string(np, "propname", prop, s)
        printk("String value: %s\n", s);
