[PATCH] virt: sevguest: add CONFIG_CRYPTO dependency

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

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':

Fixes: d63670d23e60 ("virt: sevguest: Rename the sevguest dir and files to sev-guest")
