Add support for the Inline Crypto Engine (ICE) key programming interface that's needed for the ufs-qcom driver to use inline encryption on Snapdragon SoCs. This interface consists of two SCM calls: one to program a key into a keyslot, and one to invalidate a keyslot. Although the UFS specification defines a standard way to do this, on these SoCs the Linux kernel isn't permitted to access the needed crypto configuration registers directly; these SCM calls must be used instead.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
