In certain scenarios we may just want to clear the ITCT for a device, and not free other resources like the SATA bitmap using in v2 hw. To facilitate this, this patch relocates the code of clearing ITCT from free_device() to a new hw interface clear_itct(). Then for some hw, we should not realise free_device() if there's nothing left to do for it.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
