[PATCH v2 0/1] coresight: etm4x: Fix kernel / user space filtering in perf

Kernel / User mode filtering was relying on side effect of access control of default full address range filtering. This now uses the main control register to remove dependency on address filter being present as default setting.

Changes since v1: 1. created helper fn to set filter values & improved comment. 2. added fix to sysfs mode settings
