From: Jian Cai

This fixes build failures with -Wimplicit-function-declaration, e.g.

^[[1m/mnt/host/source/src/third_party/kernel/v5.4/drivers/hwtracing/coresight/coresight-syscfg.c:455:15: ^[[0m^[[0;1;31merror: ^[[0m^[[1mimplicit declaration of function 'kzalloc' [-Werror,-Wimplicit-function-declaration]^[[0m
csdev_item = kzalloc(sizeof(struct cscfg_registered_csdev), GFP_KERNEL);
^[[0;1;32m ^
