Adopt pinctrl support to leds-gpio driver based on leds-gpio
device pointer, pinctrl driver configure SoC pins to GPIO
mode according to definitions provided in .dts file.

Thanks for this, actually Marek Vasut submitted a similar patch
before. I'm pretty fine with this patch.

Thanks for submitting this actually ... I didn't have time to properly 
investigate this.

But without proper DT setting, it will also give us warning I think.
or we can provide some dummy functions as a temp solution as Shawn
pointed out before.

But this driver is also used on hardware that's not yet coverted to DT, so I'd 
say dev_warn() if CONFIG_OF is enabled and otherwise simply go on ? Actually, 
can we not skip whole this pinctrl thing if CONFIG_OF is disabled? Actually (2), 
what's the relationship between OF and pinctrl?

The warning should be pinctrl related as the pinctrl drivers may not be
device tree based drivers.

Tony
