coresight: Fixes device's owner field for registered using coresight_init_driver()
The coresight_init_driver() of the coresight-core module is called from the sub coresgiht device (such as tmc/stm/funnle/...) module. It calls amba_driver_register() and Platform_driver_register(), which are macro functions that use the coresight-core's module to initialize the caller's owner field. Therefore, when the sub coresight device calls coresight_init_driver(), an incorrect THIS_MODULE value is captured. The sub coesgiht modules can be removed while their callbacks are running, resulting in a general protection failure. Add module parameter to coresight_init_driver() so can be called with the module of the callback.
