ASoC: cros_ec_codec: fix kconfig dependency warning for SND_SOC_CROS_EC_CODEC

[ Upstream commit 50b18e4a2608e3897f3787eaa7dfa869b40d9923 ]

When SND_SOC_CROS_EC_CODEC is enabled and CRYPTO is disabled, it results
in the following Kbuild warning:

WARNING: unmet direct dependencies detected for CRYPTO_LIB_SHA256
  Depends on [n]: CRYPTO [=n]
  Selected by [y]:
  - SND_SOC_CROS_EC_CODEC [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && CROS_EC [=y]

The reason is that SND_SOC_CROS_EC_CODEC selects CRYPTO_LIB_SHA256 without
depending on or selecting CRYPTO while CRYPTO_LIB_SHA256 is subordinate to
CRYPTO.

Honor the kconfig menu hierarchy to remove kconfig dependency warnings.
