arm64: dts: ti: k3-j784s4-j742s2-main-common.dtsi: Refactor watchdog instances for j784s4

Each A72 core has one watchdog instance associated with it. Since j742s2
has 4 A72 cores, the common file should not define 8 watchdog instances.

Refactor the last 4 extra watchdogs from the common file to j784s4
specific file, as j784s4 has 8 A72 cores and thus hardware description
requires 8 watchdog instances.
