Accordingly I could merge these patches on top of your commits and send them to Greg.

Also without a platform device, it cannot be probed and bound to a platform driver. This creates a dummy platform device for TRBE after ascertaining that ACPI provides required interrupts uniformly across all cpus on the system. This device gets created inside drivers/perf/arm_pmu_acpi.c to accommodate TRBE being built as a module.

Hence this refactors arm_spe_acpi_register_device() into a common helper arm_acpi_register_pmu_device().
