soc: qcom: watchdog_v2: Increase timeout for forced bites (again)

The amount of time we wait for a reset following an attempted
forced watchdog bite was recently increased from 1ms to 2s. As
it turns out, this is not enough when certain debug features
(ex. cache dumping are enabled) as the secure software executing
in EL3 may take close to 10 seconds to complete collection of
dumps.  Therefore, increase the wait to 10s.
