The macro function of_match_ptr() is NULL if CONFIG_OF is not set, in this
case Clang compiler would complain the of_device_id variable is unused.

The hardware spinlock devices are defined in the DT, there's no need for
init calls order, remove boilerplate code by using module_platform_driver.

Since the hwspinlock core has changed the PM runtime to be optional, thus
remove the redundant PM runtime implementation in the Spreadtrum hwlock
driver.

Use devm_hwspin_lock_register() to register the hwlock controller instead of
unregistering the hwlock controller explicitly when removing the device.

clk_disable_unprepare()
Use devm_add_action_or_reset() for calls to clk_disable_unprepare(),
which can simplify the error handling.

We must check the return value of clk_prepare_enable() to make sure the
hardware spinlock controller can be enabled successfully, otherwise we
should return error.

Use the new helper that wraps the calls to platform_get_resource()
and devm_ioremap_resource() together, which can simpify the code.
