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.
Fixes: 6969d1d9c615 ("ARM: dts: qcom-apq8064: Set 'cxo_board' as ref clock of the DSI PHY")
