Introduce `dphy_conf_clks` and `dphy_mode_clk_check` callbacks in `rzg2l_mipi_dsi_hw_info` to configure the VCLK and validate supported display modes. On the RZ/V2H(P) SoC, the DSI PLL dividers need to be as accurate as possible. To ensure compatibility with both RZ/G2L and RZ/V2H(P) SoCs, function pointers are introduced. Modify `rzg2l_mipi_dsi_startup()` to use `dphy_conf_clks` for clock configuration and `rzg2l_mipi_dsi_bridge_mode_valid()` to invoke `dphy_mode_clk_check` for mode validation. This change ensures proper operation across different SoC variants by allowing fine-grained control over clock configuration and mode validation.

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.
