[PATCH v2 3/4] dt-bindings: led: add virtual LED bindings

[Jonathan Brophy]

From: Jonathan Brophy <professor_jonny@xxxxxxxxxxx>

Add device tree bindings for virtual LED groups.

The use of the virtual status function identifier allows users to distinguish
virtual LEDs from real LEDs in sysfs.

If a virtual LED and a real LED are triggered at the same time, an undefined
state may occur. Therefore, it is assumed that hardware LEDs are blocked when
a LED is under the control of a virtual LED driver.

Having its own function definition helps reduce ambiguity and improves
clarity in LED behavior and trigger resolution.
