Subject: [v1] arm64: dts: qcom: sc7280: assign DSI clock source parents

This change is needed after the refactor done by the patch [2]
(drm/msm/dsi: stop setting clock parents manually) of series [1],
to fix the DSI pixel clock set rate error:
dsi_link_clk_set_rate_6g: Failed to set rate pixel clk, -22
msm_dsi_host_power_on: failed to enable link clocks. ret=-22
