The Allwinner A523 SoC introduces some new MP-style mod clock, where the second "P" divider is an actual numerical divider value, and not the numbers of bits to shift (1..32 instead of 1,2,4,8). The rest of the clock is the same as the existing MP clock, so enhance the existing code to accommodate for this. Introduce the new CCU feature bit CCU_FEATURE_DUAL_DIV to mark an MP clock as having two dividers, and change the dividing and encoding code to differentiate the two cases.

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.
