The DP PHYs on X1E80100 need the refclk which is provided by the TCSR CC. So add it to the PHYs.

You want to backport this to 6.9, but you also want to backport the driver patch to 6.10, "meh"

I'm not sure it makes sense to backport functionally, as this would only exhibit issues if:

a) the UEFI did no work to enable the refclk or: b) unused cleanup would happen

but the board would not survive booting with b) in v6.9, at least it wouldn't have display - see Commit b60521eff227 ("clk: qcom: gcc-x1e80100: Unregister GCC_GPU_CFG_AHB_CLK/GCC_DISP_XO_CLK")

and a) is not something we'd hit on any of the upstream-supported targets
