common/board_f.c: fix compile error when tracing disabled

From: Kevin Hilman <[email protected]>

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 the call to trace_early_init() with #ifdef CONFIG_TRACE.

Applies to v2015.01-rc3

v2: Also remove the static inline stuff from trace.h
