Use this instead of <code class="function">platform_driver_register</code> when you know the device
is not hotpluggable and has already been registered, and you want to
remove its run-once <code class="function">probe</code> infrastructure from memory after the driver
has bound to the device.
</p><p>
One typical use for this would be with drivers for controllers integrated
into system-on-chip processors, where the controller devices have been
configured as part of board setup.
</p><p>
Returns zero if the driver registered and bound to a device, else returns
a negative error code and with the driver not registered.
