In ARM v8.2 the cache will turn off automatically when cpu power down.
Therefore use the spin_lock instead of bakery_lock for the platform in
which HW_ASSISTED_COHERENCY is enabled.
In Versal NET platform HW_ASSISTED_COHERENCY is enabled so it will use
spin lock. In ZynqMP and Versal HW_ASSISTED_COHERENCY is not enabled so
it will use bakery_lock.
Also remove bakery_lock_init() because it is empty.
