    ipq40xx: add LED functions for Google WiFi
    
    Add LED function properties for the LED controller to avoid failing
    driver probe with kernel 5.15.
    
    While at it, also define the OpenWrt LED indicator patterns for this
    device.
    
    Ref commit 583ac0e11df7 ("mpc85xx: update lp5521 led-controller node for 5.10")
    
    Google uses white for running and red for an issue
