Hung-Te Lin 9497fcb742 cbfstool: Change FMD annotation to flags
The idea of "annotation" for firmware sections was pretty flexible, but
in future we will want multiple attributes applied to same area. For
example, indicate the section must be preserved when updating firmware
so serial number or MAC address can be preserved.

The solution here is to extend annotation so it can take multiple
identifiers (flags) in a row. For example, to declare a 64KB COREBOOT
section as CBFS using annotation:

 COREBOOT(CBFS)@0x0 64k

If there's a new flag "PRESERVE" indicating the section must be
preserved before update, we can declare it following CBFS flag:

 COREBOOT(CBFS PRESERVE)@0x0 64k

The flags are directly parsed in fmd_parser, and stored in an union
flashmap_flags. Output modules can choose to ignore or process the
flags.

Currently the only supported flag is "CBFS" (for backward compatible
with annotation). There will be more new flags in follow up patches.
