[PATCH v4 14/20] coresight: remove multiple init calls from replicator driver

From: Mian Yousaf Kaukab <ykaukab at suse.de>
Dynamic-replicator uses module_amba_driver to register. Whereas
static-replicator uses builtin_platform_driver. Combine these init
calls into a single module_init/exit pair in preparation to make the
driver modular.
