This series is based on next-20230116.

TOPRGU = Top Reset Generation Unit

In some cases, we may need TOPRGU to reset the wdt timer after system
resets. Provide a reset_by_toprgu parameter for configuration. We can
disable or enable it by adding reset_by_toprgu in dts.

Changes since v2:
 - Correct the description
Changes since v1:
 - Add more information in bindings
 - Modify some words in the commit message
