coresight: replicator: Move ACPI support from AMBA driver to platform driver
Add support for the dynamic replicator device in the platform driver, which
can then be used on ACPI based platforms. This change would now allow
runtime power management for replicator devices on ACPI based systems.
The driver would try to enable the APB clock if available. Also, rename the
code to reflect the fact that it now handles both static and dynamic
replicators. But first this refactors replicator_probe() making sure it can
be used both for platform and AMBA drivers, by moving the pm_runtime_put()
to the callers.
