crypto: ccp - Fix SEV_VERSION_GREATER_OR_EQUAL

[ Upstream commit 83bf42510d7f7e1daa692c096e8e9919334d7b57 ]

SEV_VERSION_GREATER_OR_EQUAL() will fail if upgrading from 2.2 to 3.1, for
example, because the minor version is not equal to or greater than the
major.

Fix this and move to a static inline function for appropriate type
checking.
