[net-next,v2,00/14] net: Add basic LED support for switch/phy

This is a continue of [1]. It was decided to take a more gradual
approach to implement LEDs support for switch and phy starting with
basic support and then implementing the hw control part when we have all
the prereq done.

This series implements only the brightness_set() and blink_set() ops.
An example of switch implementation is done with qca8k.

For PHY a more generic approach is used with implementing the LED
support in PHY core and with the user (in this case marvell) adding all
the required functions.

Currently we set the default-state as "keep" to not change the default
configuration of the declared LEDs since almost every switch have a
default configuration.

Changes in new series v2:
- Add LEDs node for rb3011
- Fix rb3011 switch node unevaluated properties while running 
  make dtbs_check
- Fix a copypaste error in qca8k-leds.c for port 4 required shift
- Drop phy-handle usage for qca8k and use qca8k_port_to_phy()
- Add review tag from Andrew
- Add Christian Marangi SOB in each Andrew patch
- Add extra description for dsa-port stressing that PHY have no access
  and LED are controlled by the related MAC
- Add missing additionalProperties for dsa-port.yaml and ethernet-phy.yaml

Changes from the old v8 series:
- Drop linux,default-trigger set to netdev.
- Dropped every hw control related patch and implement only
  blink_set and brightness_set
- Add default-state to "keep" for each LED node example
