led: gpio: Check device compatible string to determine the top level node

Browse source 
Since 2d1deaf88e ("led: gpio: Drop duplicate OF "label" property parsing"),
all LED nodes have some sort of label. Use device_is_compatible(..."leds-gpio")
to determine whether this is a top-level node, since it is only the top
level node which is compatible with "leds-gpio", the GPIO LEDs subnodes
are not.

Fixes: 2d1deaf88e ("led: gpio: Drop duplicate OF "label" property parsing")
