Move LED active-low property to common.yaml. This property is currently defined multiple times by bcm LEDs. This property will now be supported in a generic way for PHY LEDs with the use of a generic function. With active-low bool property not defined, active-high is always assumed.

|
This LEDs controller was first used on BCM63138 and later reused on BCM4908,
|
|
BCM6848, BCM6858, BCM63138, BCM63148, BCM63381 and BCM68360 SoCs.
|
|
|
|
It supports up to 32 LEDs that can be connected parallelly or serially. It
|
|
also includes limited support for hardware blinking.
|
|
|
|
Binding serially connected LEDs isn't documented yet.
