We are currently using generic PSP Mailbox register for sending SHA complete command to PSP but observe random arbitration issue during PSP validation as MP0_C2PMSG_26_REG used by other kernel modules. Use separate mailbox registers and doorbell mechanism to send SHA_DMA complete command to PSP. This fixes such validation issues and added flexibility for sending more ACP commands to PSP in future as new mbox registers i.e MP0_C2PMSG_114_REG and MP0_C2PMSG_73_REG are dedicated by PSP for ACP communications.
