Log Message:
rk3399: add definition for the watchdog timer clock gate
The watchdog timer clock gate is a bit special because it's a secure
gate that can only be accessed from EL3. We still need a dummy gate
definition for it so that dwcwdt(4) can infer the frequency via the
parent clock. The gate is enabled by default by U-Boot.
