    ipq40xx: Lyra: update RGB LED-Controller node for 5.10+
    
    Add the reg and color property to each channel node. This
    update is to accommodate the multicolor framework.
    
    Refer to:
    <https://lore.kernel.org/all/20200622185919.2131-9-dmurphy@ti.com>
    <https://lore.kernel.org/all/20210818070209.1540451-1-michal.vokac@ysoft.com>
    
    Note:
    
    There is only a single extremely bright RGB-LED.
    The RGB-color channels (i.e.: blue-0, blue-1 and blue-2)
    are running in parallel to increase the current delivery
    beyond what a single PWM-output on the LED controller
    could do.
