The SP805 binding sets the name for the actual watchdog clock to "wdog_clk" (with an underscore). Change the name in the DTs for ARM Ltd. platforms to match that. The Linux and U-Boot driver use the *first* clock for this purpose anyway, so it does not break anything. For MPS2 we only specify one clock so far, but the binding requires two clocks to be named. In practice, Linux would pick a clock named "apb_pclk" for the bus clock, and the Linux and U-Boot SP805 driver would use the first clock to derive the actual watchdog counter frequency. So since currently both are the very same clock, we can just double the clock reference, and add the correct clock-names, to match the binding.
