The SP805 DT binding requires two clocks to be specified, but the Broadcom Cygnus DT currently only specifies one clock. 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. 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.
