Prior SPL pass control to U-Boot, SPL will send a mailbox command
"HPS_STAGE_NOTIFY" to notify Secure Device Manager (SDM) on HPS SW
transition.
The purpose is for debug as user can query SDM on HPS error details
when HPS enters a warm reset due to error such as watchdog.

You should put this notify into spl_perform_fixups(), so this can used by both boot flows:
SPL -> U-Boot and SPL -> ATF -> U-Boot.
