Subject: [PATCH v4 0/2] Add reaction control in rti

This allows for reaction control in rti driver. Since AM62L SoC [0]
does not have WWD reset output routed to a ESM module like all other
K3 SoC's and has the reset output signal routed to the reset HW block,
add a new compatible for AM62L and configure reset reaction for AM62L
SoC instead of NMI.

This patch has been tested on AM62L EVM [1].

Changes since v3:
- Expected default reaction for watchdog is HW reset line, so check for NMI
  and set reaction to NMI if exists, else default to HW reset.
