[PATCH 3/3] trace: fix four sparse warnings

[Dmitri Vorobiev <dmitri.vorobiev@movial.com>]

Impact: cleanup.

This patch fixes the following sparse warnings:

kernel/trace/trace.c:385:9: warning: symbol 'trace_seq_to_buffer' was
not declared. Should it be static?

kernel/trace/trace_clock.c:29:13: warning: symbol 'trace_clock_local'
was not declared. Should it be static?

kernel/trace/trace_clock.c:54:13: warning: symbol 'trace_clock' was not
declared. Should it be static?

kernel/trace/trace_clock.c:74:13: warning: symbol 'trace_clock_global'
was not declared. Should it be static?
