ec9aa8971f leds: rgb: leds-group-multicolor: Allow LEDs to stay on in suspend
If none of the managed LEDs enable LED_CORE_SUSPENDRESUME, then we
shouldn't need to set it here. This makes it possible to use multicolor
groups with GPIO LEDs that enable retain-state-suspended in the device
tree.

37d0849ed3 leds: rgb: Add a multicolor LED driver to group monochromatic LEDs
Grouping multiple monochrome LEDs into a multicolor LED device has a few
benefits over handling the group in user-space:
- The state of the LEDs relative to each other is consistent. In other
  words, if 2 threads competes to set the LED to green and red, the
  end-result cannot be black or yellow.
- The multicolor LED as a whole can be driven through the sysfs LED
  interface.
