coresight: tpiu: Move ACPI support from AMBA driver to platform driver
Add support for the tpiu device in the platform driver, which can then be
used on ACPI based platforms. This change would now allow runtime power
management for ACPI based systems. The driver would try to enable the APB
clock if available. But first this renames and then refactors tpiu_probe()
and tpiu_remove(), making sure it can be used both for platform and AMBA
drivers. This also moves pm_runtime_put() from tpiu_probe() to the callers.
While here, this also sorts the included headers in alphabetic order.
