[PATCH v5 1/2] dt-bindings: arm: Add new compatible for smc/hvc transport for SCMI

Introduce compatible "qcom,scmi-smc" for SCMI smc/hvc transport channel for
Qualcomm virtual platforms.

This compatible mandates populating an additional parameter 'capability-id'
from the last 8 bytes of the shmem channel.
