arm64: dts: qcom: sm8650-hdk: Add support for the Rear Camera Card overlay

To provide access to camera sensors a Rear Camera Card can be connected
to SM8650-HDK board, the camera sensors are:
* Samsung S5K33D ToF camera sensor, connected to CSI0 over MIPI D-PHY,
* Sony IMX766 Wide camera sensor, connected to CSI1 over MIPI C-PHY,
* Omnivision OV64B Ultrawide camera sensor, connected to CSI2 over MIPI C-PHY,
* Samsung S5KJN1 Tele camera sensor, connected to CSI3 over MIPI D-PHY).

Get the initial support of Samsung S5KJN1 camera sensor and two flash leds
on the Rear Camera Card board by adding a board overlay.
