This changes an existing nodename into something that is still not the
preferred way. In the current Rockchip dts there are nodenames like
'work', 'yellow' that causing warnings with the command:

make -k ARCH=arm dtbs_check

Could you give a generic guide line/example, so all these changes are
treated the same way? As if the naming follows the preferred 'led-0' line.
