regulator: Revert "Use driver_deferred_probe_timeout for regulator_init_complete_work"

This reverts commit dca0b44957e5 ("regulator: Use
driver_deferred_probe_timeout for regulator_init_complete_work"),
as we ended up reverting the default deferred_probe_timeout
value back to zero, to preserve behavior with 5.6 we need to
decouple the regulator timeout which was previously 30 seconds.

This avoids breaking some systems that depend on the regulator
timeout but don't require the deferred probe timeout.
