This series enables detection of ACPI based TRBE devices via a stand alone
purpose built representative platform device. But as a pre-requisite this
changes coresight_platform_data structure assignment for the TRBE device.

This series is based on v6.5-rc1 kernel, is also dependent on the following
EDK2 changes posted earlier by Sami.
