platform_driver_probe() should be used for registering this driver only if we want to "...remove its run-once probe() infrastructure from memory after the driver has bound to the device." However, we may want to leave the probe infrastructure in place in order to support binding/unbinding a device dynamically. This is useful, for instance, as a power management mechanism, where a device can be totally powered down when unbound (whereas with runtime power management, powering down the SATA core would incur unacceptable loss of functionality). Thus, convert this driver to use platform_driver_register().
