mmc: cqhci: Add eMMC crypto APIs

Add functions to use eMMC inline encryption hardware capability
inline with JEDEC eMMC v5.2 specification and to work with
block keyslot manager. Also add crypto variant vops to handle
quirks in individual inline encryption hardware. The vops fallback
to default implementation which is JEDEC eMMC v5.2 compliant.
