drivers/hwtracing: fix coresight-etm4x implicit <module.h> usage
In commit 2e1cdfe184b5202d51e0611d7a051e2bea303946 ("coresight-etm4x: Adding CoreSight ETM4x driver") this driver was added. It uses module_amba_driver() to register itself with the system, which is just an alias for module_driver. This currently works by relying on getting that via init.h but we are planning to move that code[1] to module.h -- at which time this will fail to compile since it does not include module.h currently, resulting in: drivers/hwtracing/coresight/coresight-etm4x.c:2701:1: note: in expansion of macro ‘module_amba_driver’ module_amba_driver(etm4x_driver); ^ include/linux/device.h:1296:1: error: type defaults to ‘int’ in declaration of ‘module_init’ [-Werror=implicit-int] module_init(__driver##_init); \ ^ In the future, the amba support may want to create another alias that uses builtin_driver[2] for cases like this which are using bool Kconfig triggers, but for now we just fix the implicit include.
