arm64: dts: qcom: sdm670: label the camss ports instead of endpoints

Endpoints cannot be pre-defined since commit dcf6fb8 ("media: qcom:
camss: remove a check for unavailable CAMSS endpoint") was applied,
probing all endpoint nodes and requiring them to have a remote. There is
no sensible remote in the SoC devicetree because camera sensors are
board-specific.

The ports are meant to be extended by a board devicetree in order to
define fully configured endpoints and connect the ports to camera
sensors. For nodes that are only meaningful if extended, labels are
usually assigned. Label these ports so they can be extended directly.
