[PATCH 5.13 044/800] ARM: dts: ux500: Fix LED probing
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Linus Walleij <redacted>
commit 7749510c459c10c431d746a4749e7c9cf2899156 upstream.
The Ux500 HREF LEDs have not been probing properly for a
while as this was introduce:
ret = of_property_read_u32(np, "color", &led_color);
if (ret)
return ret;
Since the device tree did not define the new invented color
attribute, probe was failing.
Define color attributes for the LEDs so they work again.
