In the upstream kernel, BLK_CRYPTO_KEY_TYPE_HW_WRAPPED was added in
v6.15 and has never been the default.  Also currently only ufs-qcom and
msm-sdhci support it.  ufs-exynos, ufs-mediatek, mtk-sd, ufs-sprd,
ufshcd-pci currently support raw keys only.

It should be supported, just as an opt-in thing.
