This patch series adds support for inline encryption to UFS using
the inline encryption support in the block layer. It follows the JEDEC
UFSHCI v2.1 specification, which defines inline encryption for UFS.
This patch series is based on v5.8-rc1.

Patch 1 introduces the crypto registers and struct definitions defined
in the UFSHCI v2.1 spec.

Patch 2 introduces functions to manipulate the UFS inline encryption
hardware (again in line with the UFSHCI v2.1 spec) via the block
layer keyslot manager. Device specific drivers must set the
UFSHCD_CAP_CRYPTO in hba->caps before ufshcd_hba_init_crypto is called
to opt-in to inline encryption support.

Patch 3 wires up ufshcd.c with the UFS crypto API introduced in Patch 2.
