Mostafa Saleh 070e326f32 iommu/arm-smmu-v3-test: Test masters with stall enabled
At the moment, the SMMUv3 unit tests assume ATS is always enabled,
although this is sufficient to test hitless/non-hitless transitions,
but exercising other features is useful to check ste/cd population
logic (for example the .get_used logic).

Add an enum where bits define features per-master, at the moment there
is only ATS and STALLs which are mutually exclusive, but this would
make it easier to extend with other features in the future.

Also, Add 2 more tests for s1 <-> s2 transitions with stalls enabled.

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.
