[ Upstream commit 647d41d3952d726d4ae49e853a9eff68ebad3b3f ]
vmx-crypto module depends on CRYPTO_AES, CRYPTO_CBC, CRYPTO_CTR or CRYPTO_XTS, thus add them.
These dependencies are likely to be enabled, but if CRYPTO_DEV_VMX=y && !CRYPTO_MANAGER_DISABLE_TESTS and either of CRYPTO_AES, CRYPTO_CBC, CRYPTO_CTR or CRYPTO_XTS is built as module or disabled, alg_test() from crypto/testmgr.c complains during boot about failing to allocate the generic fallback implementations (2 == ENOENT):
