arm64: dts: qcom: sm8550-hdk: Add SM8550-HDK Rear Camera Card overlay

Lantronix SM8550-HDK board may be equipped with a Rear Camera Card PCB
which contains:
* Samsung S3K33D time-of-fligt image sensor connected to CSIPHY0 (TOF),
* Omnivision OV64B40 image sensor connected to CSIPHY1 (uWide),
* Sony IMX766 image sensor connected to CSIPHY2 (Wide),
* Samsung S5K3M5 image sensor connected to CSIPHY3 (Tele),
* two flash leds.

The change adds support of a Samsung S5K3M5 camera image sensor and
two flash leds on the external camera card module.
