Subject: crypto: ccp - Drop TEE support for IRQ handler
Git-commit: a7ca7bbdb59e59a7890116e03a3bb99bcf4c87a6
Patch-mainline: v6.4-rc1
References: jsc#PED-7167
The only PSP mailbox that currently supports interrupt on completion
is the SEV mailbox. Drop the dead code for the TEE subdriver to
potentially call it.
