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 V2:

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

Changes in V1:

FYI: if you pass '--cc-cover' to git send-email, it will CC all these
folks on the series, which I think is better when you're reviewing stuff
(I didn't receive patches 3 and 4).

My bad, forgot --cc-cover on the command line.
