watchdog: ulp_wdog: Use driver model for reset_cpu()
Replace hardcoded WDOG_BASE_ADDR with driver model based dynamic address
lookup from device tree, allowing reset_cpu() to dynamically locate
watchdog devices from device tree.
This change also enables CONFIG_WDT for relevant boards and ensures the
watchdog nodes are available for driver model usage.
- Remove hardcoded WDOG_BASE_ADDR from hw_watchdog_* functions
- Reimplement reset_cpu() using UCLASS_WDT device iteration
- Add ulp_wdt_expire_now() callback for standard WDT interface
- Pass wdog register pointer to hw_watchdog_set_timeout()
- Enable CONFIG_WDT for boards using ULP watchdog
- Remove wdog3 status = "disabled" overrides from U-Boot device tree
overlays, as the watchdog device needs to be accessible for driver
model based reset functionality.
