Use the register mapping feature bit

Browse Source 
All functions which just call probe_jedec and then map flash registers
are replaced by probe_jedec. All functions which call probe_jedec, map
flash registers and do something else can at least eliminate mapping
flash registers.
Fix logic inversion in probe_jedec to map flash registers on success
instead of on failure.
Change a few TIMING_IGNORED to TIMING_FIXME where probe_jedec is used.

Total savings: One probe function simplified, three probe functions
eliminated.

Corresponding to flashrom svn r839.
