> Changed MBOX_CLIENT_ID_UBOOT to be the same with ATF's mailbox
> client ID so that SDM can treat them as same client for related
> request. Otherwise, under some specific cases, like QSPI_OPEN in
> SPL stage used different client ID with ATF's client ID for QSPI
> exclusive access, then following QSPI access like QSPI_CLOSE via
> SMC call to ATF will fail.
