......................................................................

Add SPI trace map support

with -M you can specify a map file that will be used to print which
section of the flash your SPI accesses go to. The format of the map
file is simple:

Start (hex)    End (hex)    Length (hex)    Area Name
-----------    ---------    ------------    ---------
00000000       01FFFFFF     02000000        Full Flash Image
00000000       00000FFF     00001000        Descriptor Region
00000014       00000017     00000004            FLMAP0 - Flash Map 0 Register
00000018       0000001B     00000004            FLMAP1 - Flash Map 1 Register
[..]
00500000       01FFFFFF     01B00000        BIOS Region
00500000       00cfffff     00800000            RW_SECTION_A
00500000       0050ffff     00010000            VBLOCK_A
00510000       009fffbf     004effc0            FW_MAIN_A
009fffc0       009fffff     00000040            RW_FWID_A
[..]
01805000       01874fff     00070000            GBB
01875000       01ffffff     0078b000            COREBOOT

Right now the section is only printed in brief mode.
