f9dc67d18e led: add TI LP5562 LED driver
Driver for the TI LP5562 4 channel LED controller. Supports
independent on/off control of all 4 channels. Supports LED_BLINK on 3
independent channels: blue/green/red. The white channel can blink, but
shares the blue channel blink rate.

Heavily based on patch originally from Doug Zobel [1].

I have modified it so it matches the DT bindings in the linux tree,
and also follows the linux driver implementation more closely. This
should address Tom's concerns, and also matches my goal of making the
U-Boot driver work with our existing .dts which is known to work in
linux.

As our boards only have the R,G,B outputs connected, I have not
actually tested how the white channel behaves, but the R,G,B work
exactly as expected.

d00c6a2d56 led: add initial support for bcm6858
The driver add the support of the led IP on bcm6858.
This led IP can drive up to 32 leds, and can handle
blinking.

5917112c9e dm: Add support for LEDs
Add a simple uclass for LEDs, so that these can be controlled by the device
tree and activated when needed. LEDs are referred to by their label.

This implementation requires a driver for each type of LED (e.g GPIO, I2C).
