[PATCH v3 0/6] Add and fix ESM nodes

The following patch adds ESM nodes and fixes ESM source
interrupts for Sitara K3 platforms. Currently watchdog cannot
reset the CPU because of misconfiguration or missing ESM node
in DT.

ESM node was added for am62ax and am65x. For am62px ESM source
interrupts are fixed. Comments were also added for clarity on what
source interrupts are routed to ESM based on device TRM.

ESM nodes like MCU ESM for am65x are added for device completion,
currently, some ESM0 events are not routed to MCU ESM, so watchdog
cannot reset the CPU using the current implementation.

Changes since v2:
- Fix commit message for patch 6/6
- cc linux-arm-kernel
