coresight: tmc: Move ACPI support from AMBA driver to platform driver

Add support for the tmc devices 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 tmc_probe()
and tmc_remove(), making sure it can be used both for platform and AMBA
drivers. This also moves pm_runtime_put() from tmc_probe() to the callers.
