[PATCH v2] arm64: dts: qcom: eliza: Connect USB3 PHY pipe clock to GCC

[Abel Vesa]

The GCC USB3 primary PHY pipe clock is sourced by the USB3 pipe output of
the USB/DP QMP PHY. The corresponding GCC clock input was left as an
empty clock specifier when the USB nodes were added.

Connect the QMP PHY USB3 output to GCC so the USB3 PHY pipe clock can
propagate to the USB controller.

Fixes: 88ddafb01ec0 ("arm64: dts: qcom: eliza: Describe the ADSP and USB related nodes")

Changes in v2:
- Fixed the usage of wrong index. Was using the phy index instead of
  clock one.
- Picked up Konrad's R-b tag.
- Link to v1: https://patch.msgid.link/20260825-dts-qcom-eliza-add-missing-usb-dp-phy-clk-to-gcc-v1-1-f0d3719f798c@oss.qualcomm.com
