MIPS: JZ4780: dts: Fix watchdog node 

- The previous node requested a memory area of 0x100 bytes, while the
  driver only manipulates four registers present in the first 0x10 bytes.

- The driver requests for the "rtc" clock, but the previous node did not
  provide any.

reg: Register address and length for watchdog registers
clocks: phandle to the RTC clock
