Functions cc_mkenc()/cc_mkdec() were introduced in commit b577f542f93c
("x86/coco: Add API to handle encryption mask") to handle encryption
masks in page tables. As part of the above commit only cc_mkdec() was
exported, however this creates an asymmetry where a module can use
pgprot_decrypted() but not pgprot_encrypted(). Export cc_mkenc() as well
to avoid the problem.

As an example of a module using pgprot_encrypted() I tried to compile
https://github.com/draios/sysdig but I could not because of missing
cc_mkenc().
