    ARM: dts: imx6ull-dhcor: Set and limit the mode for PMIC buck 1, 2 and 3
    
    [ Upstream commit 892943d7729bbfb2edeed9e323eba9a5cec21c49 ]
    
    According to Renesas Electronics (formerly Dialog Semiconductor), the
    standard AUTO mode of the PMIC DA9061 can lead to stability problems
    depending on the hardware revision. It is recommended to set a defined
    mode such as PFM or PWM permanently. So set and limit the mode for
    buck 1, 2 and 3 to a fixed one.
