Andrey Smirnov 796114f5c5 crypto: caam - make sure clocks are enabled first
In order to access IP block's registers we need to enable appropriate
clocks first, otherwise we are risking hanging the CPU.

The problem becomes very apparent when trying to use CAAM driver built
as a kernel module. In that case caam_probe() gets called after
clk_disable_unused() which means all of the necessary clocks are
guaranteed to be disabled.

Coincidentally, this change also fixes iomap leak introduced by early
return (instead of "goto iounmap_ctrl") in commit
41fc54afae70 ("crypto: caam - simplfy clock initialization")

Tested on ZII i.MX6Q+ RDU2

Fixes: 176435ad2a ("crypto: caam - defer probing until QMan is available")

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.
