drivers/hwtracing: make coresight-* explicitly non-modular
None of the Kconfig currently controlling compilation of any of the files here are tristate, meaning that none of it currently is being built as a module by anyone. We need not be concerned about .remove functions and blocking the unbind sysfs operations, since that was already done in a recent commit. Lets remove any remaining modular references, so that when reading the drivers there is no doubt they are builtin-only. All drivers get mostly the same changes, so they are handled in batch. Changes are (1) convert to builtin_amba_driver, (2) delete module.h include where unused, and (3) relocate the description into the comments so we don't need MODULE_DESCRIPTION and associated tags. The etm3x and etm4x use module_param_named, and have been adjusted to just include moduleparam.h for that purpose. In commit f309d4443130bf814e991f836e919dca22df37ae ("platform_device: better support builtin boilerplate avoidance") we introduced the builtin_driver macro. Here we use that support and extend it to amba driver registration, so where a driver is clearly non-modular and builtin-only, we can update with the simple mapping of module_amba_driver(...) ---> builtin_amba_driver(...) Since module_amba_driver() uses the same init level priority as builtin_amba_driver() the init ordering remains unchanged with this commit.
