Introduce device tree overlays for supporting the eMMC (RTK0EF0186B02000BJ) and microSD (RTK0EF0186B01000BJ) sub-boards connected via the CN15 connector on the RZ/V2H and RZ/V2N evaluation kits. These overlays enable SDHI0 with appropriate pin control settings, power regulators, and GPIO handling. Both sub-boards are supported using shared overlay files that can be applied to either EVK due to their identical connector layout and interface support. To support this, new DT overlay files are added: - `rzv2-evk-cn15-emmc.dtso` for eMMC - `rzv2-evk-cn15-sd.dtso` for microSD Additionally, the base DTS files for both EVKs are updated to include a fixed 1.8V regulator (`reg_1p8v`) needed by the eMMC sub-board and potential future use cases such as HDMI output.

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.
