arm64: dts: qcom: sm8550-hdk: add support for the Display Card overlay 



The SM8550-HDK board may be connected to a Display Card external PCB,
which is identical to the already supported SM8650-HDK Display Card,
it provides a VTDR6130 display with Goodix Berlin Touch controller, see
also commit bc90f56a ("arm64: dts: sm8650-hdk: add support for the
Display Card overlay") for additional details.

Two overlays are added to support SM8550-HDK plus Display Card and
SM8550-HDK plus Display Card plus Rear Camera Card setups.
