The MCU watchdog nodes have incorrect comments about being tightly
coupled with M4 cores. There are no M4 cores in the MCU domains for
AM62PX and AM62Ax devices so fix the comment accordingly.
This is a non-functional fix purely, for documentation purposes.

There are no M4 cores in MCU domain for AM62AX and watchdog nodes
are tighly coupled to R5 core, fix the comment accordingly.
