Currently with the check present in the module initialisation, it shouts on all the systems irrespective of presence of coresight trace buffer extensions. Similar to Arm SPE perf driver, move the check for kernel page table isolation from EL0 to the device probe stage instead of the module initialisation so that it complains only on the systems that support TRBE.

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.
