crypto: ccp - shutdown SEV firmware on kexec
The commit 97f9ac3db6612 ("crypto: ccp - Add support for SEV-ES to the
PSP driver") added support to allocate Trusted Memory Region (TMR)
used during the SEV-ES firmware initialization. The TMR gets locked
during the firmware initialization and unlocked during the shutdown.
While the TMR is locked, access to it is disallowed.
Currently, the CCP driver does not shutdown the firmware during the
kexec reboot, leaving the TMR memory locked.
Register a callback to shutdown the SEV firmware on the kexec boot.
Fixes: 97f9ac3db6612 ("crypto: ccp - Add support for SEV-ES to the PSP driver")
