[net-next PATCH v8 1/5] dt-bindings: net: phy: Make LED active-low property common

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.

Changes v4:
- Drop support for global active-low
- Rework to polarity option (for marvell10g series support)
Changes v3:
- Out of RFC
Changes v2:
- Add this patch
