[PATCH 3/3] arm64: dts: qcom: sm8750: Fix videocc clock inputs

[Shawn Guo]

The videocc node passes GCC_VIDEO_AHB_CLK as its second input and stops
there. videocc-sm8750.c declares its DT inputs as DT_BI_TCXO,
DT_BI_TCXO_AO and DT_SLEEP_CLK, so the second input is the always-on
board XO rather than an AHB clock, and the sleep clock is missing
entirely.

The missing third input leaves video_cc_sleep_clk_src unable to resolve
its parent, so it registers as an orphan clock and cannot be rated.
The AHB phandle in the always-on XO slot is not resolved by the driver
today, but it implies a parent relationship the hardware does not have.

Pass bi_tcxo_ao_div2 and the board sleep clock instead.
