[0/2] Fix RGB status LED and keyboard backlight LEDs on Nokia N900

The RGB status LED and keyboard backlight LEDs were broken on the Nokia N900
since the conversion to gpiod descriptors and additionally later on with the
addition of multi color support. There was at least one attempt merged to fix
the lp5523 driver since the gpiod conversion, but it doesn't honour the device
tree, which in the case of the Nokia N900 means that the fix doesn't work.

In this series are two patches fix the problems:

* One addresses the gpiod change in the device tree as well as the multi
  color support in the device tree;
* The other patch fixes the previous attempt at fixing the driver to honour
  the device tree;

Please let me know if anything seems off, and I'll be glad to make any
recommended changes, thanks!

Thank you, I took the series. But if it changes the names in
/sys/class/leds, we want to do something else.

Thanks -- just for the record (I already replied to the other email) -
the names do not change based on my testing.
