Although CONFIG_ARM_SMMU_DISABLE_BYPASS_BY_DEFAULT is a welcome tool for smoking out inadequate firmware, the failure mode is non-obvious and can be confusing for end users. Add some special-case reporting of Unidentified Stream Faults to help clarify this particular symptom. Since we're adding yet another print to the mix, also break out an explicit ratelimit state to make sure everything stays together (and reduce the static storage footprint a little).

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.
