[ Upstream commit 84b9b44b99780d35fe72ac63c4724f158771e898 ]

This driver fails to link when CRYPTO is disabled, or in a loadable
module:

WARNING: unmet direct dependencies detected for CRYPTO_GCM
WARNING: unmet direct dependencies detected for CRYPTO_AEAD2
Depends on [m]: CRYPTO [=m]
Selected by [y]:
- SEV_GUEST [=y] && VIRT_DRIVERS [=y] && AMD_MEM_ENCRYPT [=y]

x86_64-linux-ld: crypto/aead.o: in function `crypto_register_aeads':
