Subject: [net-next PATCH 00/11] 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.
