    ARM: dts: qcom: apq8064: Use 27MHz PXO clock as DSI PLL reference
    
    [ Upstream commit f1db21c315f4b4f8c3fbea56aac500673132d317 ]
    
    The 28NM DSI PLL driver for msm8960 calculates with a 27MHz reference
    clock and should hence use PXO, not CXO which runs at 19.2MHz.
    
    Note that none of the DSI PHY/PLL drivers currently use this "ref"
    clock; they all rely on (sometimes inexistant) global clock names and
    usually function normally without a parent clock.  This discrepancy will
    be corrected in a future patch, for which this change needs to be in
    place first.
