[PATCH 2/7] arm64: dts: qcom: lemans-draco-evk: Add hdmi-dual-dsi overlay

[Mohit Dsor <mohit.dsor@oss.qualcomm.com>]

Enables dual-DSI mode for the LT9611UXD HDMI bridge on top of the
single-DSI base DT.

Enables DSI1 with dual-DSI clock parents and power supplies, and
reconnects the LT9611UXD bridge port@1 to mdss0_dsi1_out. DIP Switch
SW2.5 need to be ON for this to work.
