Modify config option for SHA384.

Browse source 
Although SHA512 is currently required to enable SHA384, this
is expected to change in the future. This commit is an
intermediate step towards fully separating SHA384 and SHA512.

check_config is the only module which enforces that SHA512 is
enabled together with SHA384.
