[PATCH v3 6/8] MIPS: jz4780: dts: Fix watchdog node

[Paul Cercueil]

- 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.
