[PATCH] sony-laptop: use platform_device_unregister insony_pf_remove

From: Axel Lin
Date: Wed Jun 30 2010 - 22:15:56 EST

platform_device_unregister calls platform_device_del and platform_device_put,
thus this change is logically equivalent to original code.

I made this change because the documents in platform.c shows that:
platform_device_del and platform_device_put must _only_ be externally called
in error cases. All other usage is a bug.
