[PATCH v2] coresight: syscfg: fix compiler warnings

[Jian Cai]

This fixes warnings with -Wimplicit-function-declaration, e.g.

drivers/hwtracing/coresight/coresight-syscfg.c:455:15: error:
implicit declaration of function 'kzalloc' [-Werror,
-Wimplicit-function-declaration]
        csdev_item = kzalloc(sizeof(struct cscfg_registered_csdev),
                             GFP_KERNEL);
