Update the RZ/G2L MIPI DSI driver to calculate HSFREQ using the actual
VCLK rate instead of the mode clock. The relationship between HSCLK and
VCLK is:
vclk * bpp <= hsclk * 8 * lanes
Retrieve the VCLK rate using `clk_get_rate(dsi->vclk)`, ensuring that
HSFREQ accurately reflects the clock rate set in hardware, leading to
better precision in data transmission.
Additionally, use `DIV_ROUND_CLOSEST_ULL` for a more precise division
when computing `hsfreq`. Also, update unit conversions to use correct
scaling factors for better clarity and correctness.
Since `clk_get_rate()` returns the clock rate in Hz, update the HSFREQ
threshold comparisons to use Hz instead of kHz to ensure correct behavior.

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.
