pmdomain: imx93-blk-ctrl: convert to devm_* only

Convert the driver to devm_ APIs only by making use of
devm_add_action_or_reset() and devm_pm_runtime_enable() to simplify the
probe error path and to drop the .remove() callback. This also ensures
that the device release order equals the device probe error path order.

Furthermore drop the dev_set_drvdata() usage since the only user was the
.remove() callback which is removed by this commit.
