There have been complaints about trace_printk.h causing more build time
for being in kernel.h. Move it out of kernel.h and place it in the headers
and C files that use it.

This patch became commit 9cbc3d9806d3 ("tracing: Remove trace_printk.h
from kernel.h") that currently is in next via

	https://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace.git trace/fixes

.

It creates a build regression for an ARCH=arc allmodconfig build:
