[PATCH] perf/smmuv3: Add platform id table for module auto loading

[Yicong Yang]

From: Yicong Yang <yangyicong at hisilicon.com>

On ACPI based system the device is probed by the name directly. If the
driver is configured as module it can only be loaded manually. Add the
platform id table as well as the module alias then the driver will be
loaded automatically by the udev or others once the device added.
