tracing: Enable "__cold" functions

Based on the commit:

  a586df06 "x86: Support __attribute__((__cold__)) in gcc 4.3"

some of the functions goes to the ".text.unlikely" section.

Looks like there's not many of them (I found printk, panic,
__ssb_dma_not_implemented, fat_fs_error), but still worth to
include I think.
