Hello,

LEDs controlled by BMCs are sometimes required to retain their state across BMC
resets. BMC resets may occur whilst the host is alive, thus the chassis and
host system remain powered up. In these two patches I define an new devicetree
property to describe the behaviour for GPIO LEDs and add support to the
leds-gpio driver.

Please review!

Cheers,

Andrew
