Subject: [PATCH v2 3/4] hwspinlock: omap: Use devm_hwspin_lock_register() helper
This will unregister the HW spinlock on module exit automatically for us,
currently we manually unregister which can be error-prone if not done in
the right order. This also allows us to remove the remove callback.
Do that here.
