Watchdog: introduce ARM SBSA watchdog driver
According to Server Base System Architecture (SBSA) specification,
the SBSA Generic Watchdog has two stage timeouts: the first signal
(WS0) is for alerting the system by interrupt, the second one (WS1) is a
real hardware reset.
More details about the hardware specification of this device:
ARM DEN0029B - Server Base System Architecture (SBSA)
This driver can operate ARM SBSA Generic Watchdog as a single stage
In the single stage mode, when the timeout is reached, your system
will be reset by WS1. The first signal (WS0) is ignored.
