[PATCH v7 5/8] Watchdog: introduce ARM SBSA watchdog driver

From: Fu Wei This driver bases on linux kernel watchdog framework, and use "pretimeout" in the framework. It supports getting timeout and pretimeout from parameter and FDT at the driver init stage. In first timeout, the interrupt routine run panic to save system context. Signed-off-by: Fu Wei
