[PATCH v8 6/7] arm64: dts: ti: k3-j721s2-main: Add the main domain watchdog instances

[Keerthy]

There are totally 9 instances of watchdog module. One each for the
2 A72 cores, one each for the 2 C7x cores, 1 for the GPU, 1 each
for the 4 R5F cores in the main domain. Keeping only the A72 instances
enabled and reserving the rest by default as they will be used by
their respective firmware.
