Extracts IOTLB and Dev-IOTLB invalidation logic from cache tag flush interfaces into dedicated helper functions. It prepares the codebase for upcoming changes to support batched cache invalidations. To enable direct use of qi_flush helpers in the new functions, iommu->flush.flush_iotlb and quirk_extra_dev_tlb_flush() are opened up. No functional changes are intended.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
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.
