Subject: [PATCH V3 0/4] coresight: trbe: Enable ACPI based devices

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-rc4 kernel, is also dependent on the following
EDK2 changes posted earlier by Sami.

https://edk2.groups.io/g/devel/message/107239
https://edk2.groups.io/g/devel/message/107241

Changes in V3:

- Changed ARMV8_TRBE_PDEV_NAME from "arm-trbe-acpi" into "arm,trbe"
- Dropped local variable 'matched'
- Replaced 'matched' with 'valid gsi' as being already matched once
- Moved find_acpi_cpu_topology_hetero_id() outside conditional check

Changes in V2:

https://lore.kernel.org/all/20230801094052.750416-1-anshuman.khandual@arm.com/

- Refactored arm_spe_acpi_register_device() in a separate patch
- Renamed trbe_acpi_resources as trbe_resources
- Renamed trbe_acpi_dev as trbe_dev
