arm64: dts: qcom: sc8280xp: fix UFS reference clocks

There are three UFS reference clocks on SC8280XP which are used as
follows:

 - The GCC_UFS_REF_CLKREF_CLK clock is fed to any UFS device connected
   to either controller.

 - The GCC_UFS_1_CARD_CLKREF_CLK and GCC_UFS_CARD_CLKREF_CLK clocks
   provide reference clocks to the two PHYs.

Note that this depends on first updating the clock driver to reflect
that all three clocks are sourced from CXO. Specifically, the UFS
controller driver expects the device reference clock to have a valid
frequency:

	ufshcd-qcom 1d84000.ufs: invalid ref_clk setting = 0
