Subject: [PATCH v5 0/2] Add reaction control in rti

This adds reaction control to the RTI watchdog driver. Since AM62L SoC [0]
does not have WWD reset output routed to an ESM module like all other
K3 SoCs and has the reset output signal routed to the reset HW block,
add a new compatible for AM62L [1] and configure reset reaction for
AM62L SoC instead of NMI.

Changes since v4 RESEND:
- Fix commit message grammar and capitalization issues
- Store only needed bool nmi field instead of pointer to match data structure
- Add NULL check for device_get_match_data() with proper error handling
- Rename data structures with SoC-specific rti_wdt prefix and add const
- Update struct documentation and clarify WDT expiration comment
