    qualcommax: ipq50xx: fix XO board clock rate for Yuncore AX850
    
    Commit 468975a985ab changed the XO board clock definition from a fixed
    clock to a fixed rate clock in the dtsi.
    
    As such, boards must use clock dividers and multipliers to calculate
    the clock rate based on the referenced parent clock.
