Subject: [PATCH v2 2/7] dt-bindings: remoteproc: qcom,sm8550-pas: Add
 Kaanapali CDSP

Add remote processor PAS loader for Kaanapali CDSP processor, compatible
with earlier SM8550 with minor difference: one more sixth "shutdown-ack"
interrupt. It is not compatible with SM8650 because one memory region
"global_sync_mem" is not managed by kernel on Kaanapali so it is removed
in the remoteproc cdsp node.
