tracing: make the trace clocks available generally
Jeremy Fitzhardinge reported this build failure:
LD .tmp_vmlinux1 arch/x86/kernel/built-in.o: In function `ds_take_timestamp': git/linux/arch/x86/kernel/ds.c:1380: undefined reference to `trace_clock_global' git/linux/arch/x86/kernel/ds.c:1380: undefined reference to `trace_clock_global'
Which is due to !CONFIG_TRACING && CONFIG_X86_DS=y.
Librarize the tracing clock code.
