[U-Boot] [PATCH v3] common/board_f.c: fix compile error when tracing disabled

[Kevin Hilman]

From: Kevin Hilman <khilman at linaro.org>

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.

Applies to v2015.01-rc3

v3: Actually remove the static inlines this time. :/
