[PATCH v3 0/1] dm-inlinecrypt: add support for hardware-wrapped keys

dm-inlinecrypt currently assumes that all keys are raw software keys.
That does not work for platforms where inline encryption expects
hardware-wrapped key material managed by secure firmware/hardware.

This series adds support for hardware-wrapped keys in dm-inlinecrypt by
introducing an optional <key_type> target argument. The flag lets
dm-inlinecrypt select the proper blk-crypto key type at key
initialization time:

- 1: BLK_CRYPTO_KEY_TYPE_RAW
- 2: BLK_CRYPTO_KEY_TYPE_HW_WRAPPED

With this change, dm-inlinecrypt can support both raw and wrapped key
deployment models without hardcoding one key ownership model.
The series also:
- updates target argument parsing to include the new required flag
- propagates the wrapped/raw state in target status output
- updates dm-inlinecrypt documentation and examples accordingly
