This moves remaining AMBA ACPI devices into respective platform drivers for
enabling ACPI based power management support. This might still require some
further changes but presented here just for some initial review & feedback.

This series applies on coresight/next coresight/for-next/queue and has been
built tested. This series has also been boot tested on a DT based coresight
device latform. Although it still requires testing on ACPI platforms.
