Conor Dooley c6f2dddfa7 clk: microchip: mpfs: use regmap for clocks 
Convert the PolarFire SoC clock driver to use regmaps instead of iomem
addresses as a preparatory work for supporting the new binding for this
device that will only provide the second of the two register regions, and
will require the use of syscon regmap to access the "cfg" and "periph"
clocks currently supported by the driver.

This is effectively a revert of commit 4da2404bb0 ("clk: microchip:
mpfs: convert cfg_clk to clk_divider") and commit d815569783 ("clk:
microchip: mpfs: convert periph_clk to clk_gate") as it resurrects the
ops structures removed in those commits, with the readl()s and
writel()s replaced by regmap_read()s and regmap_writes()s.

README 

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 reStructuredText 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.
