Commit9607beb917("clk: socfpga: gate: Add a determine_rate hook") added a determine_rate implementation set to the clk_hw_determine_rate_no_reparent, but failed to account for the internal divider that wasn't used before anywhere but in recalc_rate. This led to inconsistencies between the clock rate stored in clk_core->rate and the one returned by clk_round_rate() that leverages determine_rate(). Since that driver seems to be widely used (and thus regression-prone) and not supporting rate changes (since it's missing a .set_rate implementation), we can just report the current divider programmed in the clock but not try to change it in any way. This should be good enough to fix the issues reported, and if someone ever wants to allow the divider to change then it should be easy enough using the clk-divider helpers.

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.
