Hello maintainers and reviewers,

Patch 1 moves reset_control_deassert() before any register access to
ensure the watchdog controller is properly taken out of reset before
configuration, fixing a potential hardware access issue.

Patch 2 adds proper error handling for reset_control_deassert() to
prevent probe from continuing when reset deassertion fails, improving
diagnostics and reliability.

Patch 3 replaces manual reset control management with the
devm_reset_control_get_optional_shared_deasserted() helper, eliminating
explicit reset_control_assert() calls in error paths and remove.

Patch 4 adds reset line management during system suspend and resume,
asserting the reset before clocks are disabled and deasserting after
clocks are re-enabled to maintain consistent hardware state.

Patch 5 is a final cleanup of the resume function error handling.

Thank you!
