ramips: fix mt7688 watchdog register base addr

I found mt7688 watchdog not working. The watchdog registers are identical
for mt7621 and mt7628/mt7688. The first watchdog related register is at
0x10000100, the last one - a 16bit sized - at 0x10000128.

Set the correct register address and size in the dtsi file to get the
watchdog working.
