[ Upstream commit036177310b] Earlier version of driver used direct io remapped register read writes using readl/writel. But we need secure boot access which is only possible when registers are read & written using regmap. This is because the security bus/hook is written & coupled only with regmap layer. Switch the driver from direct readl/writel based register accesses to regmap based register accesses. Additionally, update the license headers to latest status.

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.
