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.
