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();
