[PATCH v1 0/1] dm-inlinecrypt: move to HW-wrapped key

dm-inlinecrypt currently initializes the blk-crypto key using
BLK_CRYPTO_KEY_TYPE_RAW, which implies that the provided key material
is a plaintext software key owned by the block layer.

This was requested as the first version in the link
(https://lore.kernel.org/all/20260312070110.GD2359@sol/) to have a
a easy way validating the patch.

However, now support for wrapped keys is already upstream and
on platforms where dm-inlinecrypt is used together with a
hardware-backed key source (e.g. TrustZone/TEE or other secure key
wrapping mechanisms), the key material passed down is already wrapped
and must be treated as opaque by the block layer.

Switching the blk-crypto key initialization to
BLK_CRYPTO_KEY_TYPE_HW_WRAPPED aligns dm-inlinecrypt
with hardware-backed key usage models and avoids incorrect assumptions
about key ownership and visibility.
