soc: qcom: smem: Add SMEM items for CDSP SMP2P communication.

Smem item definitions must be kept in sync with remote processors; if
the definitions do not match, item lookup can fail between processors.

Add smem item definitions so that the local definition table matches
the table on remote processors.
