In preparation for some upcoming cleverness, rework the control flow in of_iommu_configure() to minimise duplication and improve the propogation of errors. It's also as good a time as any to switch over from the now-just-a-compatibility-wrapper of_iommu_get_ops() to using the generic IOMMU instance interface directly.

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.
