When CONFIG_TRACE is disabled, linking fails with:
common/built-in.o:(.data.init_sequence_f+0x8): undefined reference to `trace_early_init'
To fix, wrap trace init calls with #ifdef CONFIG_TRACE.
While at it, remove the static inline version of the init call from
trace.h as suggested by Simon Glass, since it doesnt work.

Add a library which supports tracing of execution using built-in gcc
features and a microsecond timer. This can be used to record a list of
function which are executed, along with a timestamp for each. Later
this information can be sent to the host for processing.
