coresight: funnel: Move ACPI support from AMBA driver to platform driver
Add support for the dynamic funnel device in the platform driver, which can then be used on ACPI based platforms. This change would allow runtime power management for 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 funnels. But first this refactors funnel_probe() making sure it can be used both for platform and AMBA drivers, by moving the pm_runtime_put() to the callers.
