hwspinlock: Add devm_xxx() APIs to register/unregister one hwlock controller
This patch introduces devm_hwspin_lock_register() and devm_hwspin_lock_unregister()
interfaces to help to register or unregister one hardware spinlock controller, that
will help to simplify the cleanup code for hwspinlock drivers.
