Subject: [PATCH RESEND -next] tee: amdtee: amdtee depends on CRYPTO_DEV_CCP_DD

If CRYPTO_DEV_CCP_DD=m and AMDTEE=y, the following error is seen
while building call.c or core.c

drivers/tee/amdtee/call.o: In function `handle_unload_ta':
call.c:(.text+0x35f): undefined reference to `psp_tee_process_cmd'
drivers/tee/amdtee/core.o: In function `amdtee_driver_init':
core.c:(.init.text+0xf): undefined reference to `psp_check_tee_status

Fix the config dependency for AMDTEE here.
