[PATCH 0/7] Subject: coresight: Move remaining AMBA ACPI devices into platform driver

This moves remaining AMBA ACPI devices into respective platform drivers for
enabling ACPI based power management support. This series applies on latest
coresight/next branch. This series has been built, and boot tested on a DT
based coresight platform. Although this still requires some more testing on
ACPI based coresight platforms.
