      In case of booting Linux from CUST SBL by skipping reset of MCU R5 then Linux is not able to attach to MCU R5 in IPC-only mode as the MCU1_0 is not released by the SBL.

      The SBL should call TISCI_MSG_PROC_RELEASE in the case where MCU reset is skipped (SBL_SKIP_MCU_RESET  is defined.

      A clean release from SBL will mean that A72 Linux can call TISCI_MSG_PROC_REQUEST and attach in IPC-only mode. This will enable IPC between MCU R5 and A72.
