Subject: [PATCH] dt-bindings: mailbox: qcom-ipcc: Add bindings for physical
 client ids

Physical client IDs instead of virtual client IDs are used for qcom new
platforms in the Inter Process Communication Controller (IPCC) driver
as virtual physical mapping logic is removed in HW. Add the bindings.
