Changes in V6:

- Fixed te merge conflict

Changes in V5:

https://lore.kernel.org/all/20230817055405.249630-1-anshuman.khandual@arm.com/

- Detected zeroed parsed GSI as a mismatch but handled all zero scenario
- Changed condition check from 'if (ret < 0)' into a 'if (ret)'
- Dropped pr_warn() message after platform_device_register()

Changes in V4:

https://lore.kernel.org/all/20230808082247.383405-1-anshuman.khandual@arm.com/

- Added in-code comment for arm_trbe_device_probe()
- Reverted back using IS_ENABLED() for SPE PMU platform device
- Replaced #ifdef with IS_ENABLED() for TRBE platform device
- Protected arm_trbe_acpi_match with ACPI_PTR() - preventing a build failure
  when CONFIG_ACPI is not enabled
- Added __maybe_unused for arm_acpi_register_pmu_device() and dropped config
  checks with IS_ENABLED()

Changes in V3:

https://lore.kernel.org/all/20230803055652.1322801-1-anshuman.khandual@arm.com/

- 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
