From: Patrick Bruenn <p.bruenn at beckhoff.com>

main usecase in mind are LEDs which indicate a state like "power on".
With this patchset applied, all you have to do is:
Add a gpio-led node with 'default-state = "on";' property to your device
tree. And the LED will automatically light up during U-Boot startup.

Changes in v3:
- use ofnode_read_bool() instead of ofnode_read_string() to determine if
  LED node has the default-state property

Changes in v2:
- rebase to v2018.05-rc1
- add dm_test_led_default_state() to tests/dm/led.c
