[U-Boot] [PATCH V2 1/3] watchdog: designware: Migrate CONFIG_DESIGNWARE_WATCHDOG to Kconfig

[Marek Vasut]

Migrate CONFIG_DESIGNWARE_WATCHDOG to Kconfig and update the headers
accordingly, no functional change. The S10 enables the WDT only in
SPL, but does not enable it in U-Boot itself, hence disable it in
the config again.
