From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx> Update the watchdog minimum timeout value to be derived from `max_hw_heartbeat_ms` using `DIV_ROUND_UP()` to ensure a valid and consistent minimum timeout in seconds. This avoids hardcoding a value of `1` second and allows the driver to adapt correctly to different hardware configurations that may set `max_hw_heartbeat_ms` differently (e.g., based on the SoC clock source and divider).
