Hardware File Based Encryption (FBE) uses inline crypto
engine to encrypt the user data.
1. security/pfk: changes to support per file
encryption for f2fs using hardware crypto engine.
2. fs/ext4: adapted crypto APIs for generic crypto layer.
3. fs/f2fs: support hardware crypto engine based per file
encryption.
4. fs/crypto: export APIs to support hardware crypto
engine based per file encryption.
5. security/pfe: added wrapped key support based on
upstream changes.
Other changes made to provide support framework for per
file encryption.
Reverting commit e02a4e21f640 ("ext4: Add HW File Based
