half-twins: connect sfp cages link status to LEDs 

Directly connect the sfp drivers's (sfp.c) link up and down events to an
LED node in device-tree. This solution is a workaround to the
shortcomings of the generic led triggers framework in combination with
multiple dynamic network interfaces, hot-pluggable phys (inside sfp
modules) and the dpaa2 driver in particular.

Subject: [PATCH 16/18] leds: core: add variant of of_led_get for using
directly a led device node
The existing of_led_get function expects a handle to a device-tree node,
containing an "leds" property.
However properties refering to LEDs can potentially have different
names.
Add a new of_led_get_hack function that can directly parse a given led node.

Subject: [PATCH 17/18] net: sfp: support assigning status LEDs to SFP
connectors
Add support for turning on- and off an LED to indicate link status on
sfp ports. This is a necessary hack to work shortcomings of the generic
LED framework outlined below:
While it is generally suggested to use the generic led framework with
triggers such as netdev or phy, neither is currently useable when
combining imultiple dpaa2 network devices with sfp connectors and LEDs
controlled from GPIOs.
netdev triggers are insufficient for two reasons:
First because network devices are dynamically created and destroyed at
runtime, e.g. through NXPs restool, the names and numbering of interfaces
are never stable.
Secondly the mapping of one network interface to an led node appears to
be manual by writing the interface name - e.g. eth0 - to the sysfs entry
for a particular LED.
phy triggers are insufficient for two other reasons:
The real phy, the one inside an SFP module, is inserted at runtime,
arbitrarily by a an operator. It can exist at different i2c addresses -
or not at all e.g. for many fiber modules.
There can be a second "phy" though, on Layerscape platforms the serdes's
have are now described inside the dpmac nodes as phys, and they could
conceivably be equally aware of link status or negotiated speed.
However the phy led trigger driver is only registered from the
phy_connect or phy_attach functions when connecting an object of type
phy_device to a net_device. But the DPAA2 driver does not instantiate a
phy_device object in the first place.
