Sven Peter 6f87d4e637 iommu/dart: Remove iommu_flush_ops 
apple_dart_tlb_flush_{all,walk} expect to get a struct apple_dart_domain
but instead get a struct iommu_domain right now. This breaks those two
functions and can lead to kernel panics like the one below.
DART can only invalidate the entire TLB and apple_dart_iotlb_sync will
already flush everything. There's no need to do that again inside those
two functions. Let's just drop them.

README 

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 Restructured Text 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.
