Subject: [PATCH] drivers: firmware: efi: fix Kconfig dependency on CRYPTO

When EFI_EMBEDDED_FIRMWARE is enabled, and CRYPTO is not enabled,
Kbuild gives the following warning:

WARNING: unmet direct dependencies detected for CRYPTO_LIB_SHA256
  Depends on [n]: CRYPTO [=n]
  Selected by [y]:
  - EFI_EMBEDDED_FIRMWARE [=y] && EFI [=y]

This is because EFI_EMBEDDED_FIRMWARE selects CRYPTO_LIB_SHA256
without selecting or depending on CRYPTO, despite CRYPTO_LIB_SHA256
depending on CRYPTO.
