DM: WDT: Convert WDT driver to use DM/DTS (including SYSRESET)
This commit enables support for CONFIG_WDT in the U-Boot proper. Moreover,
the SYSRESET_WATCHDOG driver is used to support 'reset' command.
As SPL is not yet ready for DM conversion, the CONFIG_HW_WATCHDOG is
enabled for it. This allows the legacy SPL code to work properly.
