DDR50 speed mode is enabled for MMCSD in J721s2 but its Itap Delay Value is not present in the device tree. Thus, add Itap Delay Value for MMCSD High Speed DDR which is DDR50 speed mode for J721s2 SoC according to datasheet for J721s2.

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.
