From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx> 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.
