coresight: core: Allow the coresight core driver to be built as a module

Enhance coresight developer's efficiency to debug coresight drivers.
- Kconfig becomes a tristate, to allow =m
- append -core to source file name to allow module to
  be called coresight by the Makefile
- modules can have only one init/exit, so we add the etm_perf
  register/unregister function calls to the core init/exit
  functions.
- add a MODULE_DEVICE_TABLE for autoloading on boot
