I do not see this trigger and above "nand-disk" in
Documentation/devicetree/bindings/leds/common.txt.
So they're just missing from bindings doc and kernel actually supports
them?

I can only see led-control mentioned in
Documentation/devicetree/bindings/mfd/mc13xxx.txt as below.
- leds : Contain the led nodes and initial register values in property
"led-control".
But I failed to see where this property is actually defined.
