Add the cpufeature entries to detect the presence of Asymmetric MTE. Note: The tag checking mode is initialized via cpu_enable_mte() -> kasan_init_hw_tags() hence to enable it we require asymmetric mode to be at least on the boot CPU. If the boot CPU does not have it, it is fine for late CPUs to have it as long as the feature is not enabled (ARM64_CPUCAP_BOOT_CPU_FEATURE).

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.
