    drivers: firmware: fix kconfig dependency on CRYPTO
    
    When EFI_EMBEDDED_FIRMWARE is enabled and CRYPTO is disabled,
    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 depending on or selecting CRYPTO, despite that config option
    being subordinate to CRYPTO.
