Subject: [PATCH v4 1/6] tracing: Remove kallsyms.h include from linux/ftrace.h

kallsyms.h was included by ftrace.h for KSYM_NAME_LEN, but that usage
was removed by commit 3f5ec13696f [tracing/fastboot: move boot tracer
structs and funcs into their own header].

Remove kallsyms.h and have users relying on ftrace.h to include it for
them include it explicitly.
