Marek Behún 3058e283b8 fdt_support: Add fdt_for_each_node_by_compatible() helper macro 
Add macro fdt_for_each_node_by_compatible() to allow iterating over
fdt nodes by compatible string.

Convert various usages of
    off = fdt_node_offset_by_compatible(fdt, start, compat);
    while (off > 0) {
        code();
        off = fdt_node_offset_by_compatible(fdt, off, compat);
    }
and similar, to
    fdt_for_each_node_by_compatible(off, fdt, start, compat)
        code();
