[PATCH 2/6] arm64: dts: qcom: sm8250-hdk: Add LT9611UXC HDMI bridge

[ShiTou Hong <redstone.dcity@gmail.com>]

From: redstonee <1516235445@qq.com>

The sm8250-hdk has a video bridge chip LT9611UXC convertng MIPI DSI to HDMI.

Enable the i2c port of the chip, the display controller and DSI port.
Add the pinctrl of LT9611UXC's rst&irq pins.
