Like rk3288, the pclk supplying the watchdog is controlled via the SGRF register area. Additionally the SGRF isn't even writable in every boot mode.
But still the clock control is available and in the future someone might want to use it. Therefore define a simple clock for the time being so that the watchdog driver can read its rate.
