Add support for the RZ/T2H watchdog timer. The RZ/T2H requires control of the watchdog counter using the WDT Debug Control Register (WDTDCR), which allows explicitly stopping and starting the counter. This behavior differs from RZ/V2H, which doesn't have WDTDCR, so the driver is extended to handle this requirement. To support this, a new `wdtdcr` flag is introduced in the `rzv2h_of_data` structure. When set, the driver maps the WDTDCR register and uses it to control the watchdog counter in the start, stop, and restart callbacks. Additionally, the clock divisor and count source for RZ/T2H are defined to match its hardware configuration.

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.
